Abstract:

The cone pressuremeter is an in situ testing device comprising a pressuremeter mounted behind a cone penetrometer of the same diameter. Previously reported tests had indicated that the cone pressuremeter can provide measurements of soil strength, stiffness and in situ stress. The study presented in this thesis is aimed at developing methods of interpretation of the cone pressuremeter that can be applied with confidence to a variety of soil types. Carbonate sands have been the cause of significant problems associated with the design of foundations for offshore structures. A programme of cone pr

Abstract:

In geotechnical engineering, it has proven difficult to obtain reliable soil parameters for stiff clays. Laboratory testing results are often scattering due to the fissures and slickensides in these soils. Alternatively, in situ techniques offer a means to test the soils in place. This study focuses on in situ testing in Miocene stiff clays using an advanced nine strain arm self-boring pressuremeter (SBPM). This device was used to test the soils in both a self-boring and a simpler, non-boring mode (pre-bored or PBPM tests). The Miocene stiff clay was unique in that was sensitive and lacked of

Abstract:

The purposes of this study are to investigate the possible effects of variables like testing depth, length to diameter ratio of the probe, presence of disturbed annulus around the borehole etc. on the derived parameters from the pressuremeter test, and to develop possible alternative methods for the determination of undrained shear strength of cohesive soils, and cohesion and internal friction angle of intermediate geomaterials. For this purpose numerical simulations of pressuremeter test were performed. In the study, it is also aimed to investigate the effect of rock quality designation (RQD)

Abstract:

The self-boring pressuremeter which is inserted into the ground without disturbing the surrounding soil has two drawbacks. Skilled operators are needed to insert the probe into the ground without disturbing the soil, and the self-boring process requires a jetting action or a rotating cutter and drilling mud. One method of simplifying the pressuremeter installation procedure is to install the probe in a full displacement manner. A solid tip is placed oh the end of the probe and then the pressuremeter is pushed into the ground in the same manner as a cone penetrometer. This research project was

Abstract:

To reliably determine the lateral load-deflection behaviour of a piled foundation, a load test is commonly required. In-situ geotechnical tools, such as the cone penetrometer and the pressuremeter, have been successfully used to predict the lateral capacity of piles without the need for a load test. This research project investigates some of the variables involved in performing a pressuremeter test, and a procedure to predict the load-deflection relationship of laterally loaded piles is developed. For this thesis a total of eighty pressuremeter tests were conducted at five research sites. The

The cone-pressuremeter is a new site investigation device which incorporates a pressuremeter behind a standard cone penetrometer tip.

Abstract:

The cone pressuremeter is a promising new in situ testing device which combines the well known capabilities of a piezocone with a full displacement pressuremeter (FDPM). The focus of this thesis is to present results from FDPM tests performed as part of a cone pressuremeter sounding at three cohesive soil sites in the Vancouver area. The insertion of a cone pressuremeter results in a substantial amount of disturbance and the generation of excess pore pressures. As a result of the changing stress conditions, the length of the relaxation time or time delay between insertion and testing has a si

Abstract:

A decade has passed since the development of the self-boring pressuremeter (SBPM). Even though the device has been recognized by the geotechnical engineering profession as having high promise for evaluating in-situ stress-strain behavior of soils, its use is limited. In large part, this is due to the fact that there are important unanswered questions about the SBPM test. One of the major issues concerns the influence of drainage in the soil as it is sheared. In clays, the test is assumed to be undrained, but there is no way to control this other than by the rate of loading and no method has be

As testing stiff soils in the laboratory often leads to information which is not consistent with field performance, research was undertaken to determine in situ the soil properties. Among the devices which generated interest is the self-boring pressuremeter (SBPM). In this research, two stiff soils of the Commonwealth of Virginia were tested: A residual soil found in Blacksburg and a very stiff, non-fissured, and sensitive clay, of marine origin, known as the Miocene clay of the downtown Richmond area. Testing the residual soil of Blacksburg with the SBPM led to the following new operational

Abstract:

The Full-Displacement Pressuremeter (FDPM) Test is one in which a pressuremeter is installed in the soil by pushing it behind a conical tip. Earlier work had indicated that the unload-reload modulus measured with the FDPM was very similar to that obtained from self-boring pressuremeter (SBPM) testing. It had also been suggested that if the pressuremeter was capable of sufficient expansion, the interpreted soil properties would be those of the soil beyond the zone of disturbance. This study examined the factors affecting the measurement, analysis and interpretation of soil properties from FDPM

Abstract:

碩士<br>國立交通大學<br>土木工程學系<br>100<br>Because the difficulties involved in field tests in unsaturated soils, we often perform laboratory tests on reconstituted soil samples to determine the mechanical properties of unsaturated soils, such as soil water characteristic curves and shear strength under various matric suctions. However, soil water characteristic curve can be affected by stress state, disturbance, initial void ratio, and moisture content, etc. Characterization of unsaturated soils in situ can be a more desirable approach. Taking advantage of the optic fiber Bragg grating sensing tech

Abstract:

This thesis addresses the analytical interpretation of selfboring pressuremeter testing curves in sands. Emphasis is placed on the development of a new approach to analyze the data and hence to derive reliable predictions of the basic soil parameters, namely the friction angle, the lateral stress and the shear modulus. The new methodology of interpretation relies on a “curve fitting” technique to match the experimental and idealized (model) curves, from which a set of fundamental soil parameters are derived. These parameters are linked to each other in the framework of the cavity expansio
