摘要

本文对由三种不同的粘土和沙子混合物制成的81个试样进行了实验研究。为了确保初始参数一致，所有试样的初始含水量均为30%。在直剪仪上进行了两系列不同超固结比下的未固结不排水剪切试验：第一个试验旨在确定SHANSEP（应力历史和归一化土壤工程性质）参数，即S和m，第二个试验用于评估预固结压力。这项工作为研究含砂量对SHANSEP参数的影响以及研究SHANSEP程序估算的前期固结应力的可靠性提供了机会。

APPLICABILITY OF SHANSEP METHOD IN EVALUATION OF PRECONSOLIDATION PRESSURE

This article presents an experimental study on 81 specimens made from three different mixtures of clay and sand. To ensure uniform initial parameters, all specimens were prepared with an initial water content of 30%. Two series of unconsolidated undrained shear tests under different overconsolidation ratios were conducted on a direct shear apparatus: the first aims to determine the SHANSEP (Stress History and Normalized Soil Engineering Properties) parameters namely S and m, whereas the second is used for evaluating the preconsolidation pressure. This work has provided an opportunity to investigate the influence of sand content on SHANSEP parameters and moreover to study the reliability of the preconsolidation stress estimated by the SHANSEP procedure.
