Consolidation coefficient of Ningbo soft clay determined from piezocone penetration test (CPTU);

The Mechanism Study of the Consolidation Coefficient of Soils Determined by Piezocone Penetration Test;

The dissipation tests of excessive pore water pressure have been conducted in the soft soil region of the Zhujiang delta in order to discuss the feasibility and principle of determining the consolidation coefficient of the soft soil by means of the piezo-cone penetration test (CPTU).

Consolidation and permeability coefficients are key parameters in calculation and designing of foundations, CPTU and BAT-system can obtain the consolidation and permeability coefficients quickly and accurately.

Data acquisition system of piezocone penetration test(CPTU);

The coefficient of consolidation and coefficient of permeability of the Lianyungang marine clay are studied by laboratory and piezocone penetration test(CPTU) in order to evaluate the consolidation and permeability characteristics.

The piezocone penetration tests(CPTU)were performed in Lanyungang,China,and several in-situ test indexes such as undrained shear strength(Su),overconsolidation ratio(OCR) and coefficient of earth pressure at rest(K0) were calculated.

A soil engineering classification derived from the piezocone penetration test(CPTU) involves the uncertainty of correlation between soil composition and soil mechanical behavior.

Based on the data of DMT, vane shear test (VST), standard penetration test (SPT) and static cone penetration test (CPT) in Shanghai, the correlation relationship bet.

This paper introduces the pile-sinking mechanism of static-pressed pile in soft soil,analyzes the result of static cone penetration test and static load test combined with practical engineering,and proposes the problems should be noticed in engineering reconnaissance,and points out the regression pattern adopted by test pile settlement under similar geologic conditions.
