一、前言静力触探试验,由于其具有连续、快速、灵敏、直观、经济等众多优点,已越来越多地被应用于现场勘察工作中。近年来,对静力触探的研究已注意到贯入时探头周围产生的超孔隙水压力。对超孔隙水压力产生的机理和影响因素的研究,使我们有可能利用有效应力原理解释试验资料。而且利用这种超孔隙水压力的产生和消散,还可推测现场土的渗透性和固结性。本文介绍了同济大学研制的孔隙水压
I. INTRODUCTION The static penetrating test, because of its many advantages, such as continuous, rapid, sensitive, intuitive, and economic, has been increasingly used in field survey work. In recent years, studies of cone penetration have noted the excess pore water pressure generated around the probe during penetration. The study of the mechanism and influencing factors of the generation of excess pore water pressure makes it possible to interpret the experimental data using the principle of effective stress. In addition, the use of this excess pore water pressure generation and dissipation can also predict the permeability and consolidation of the in-situ soil. This article describes the pore water pressure developed by Tongji University.
