摘要

土工试验作为获取岩土体物理力学参数的基本手段，在工程设计、施工以及质量检测中起着十分重要的作用。结合多年来土工试验工作的经验体会，提出了对一些相关问题的看法。①以唐山某电厂土样为例，探讨了广泛分布于河北、内蒙古地区具有一定黏粒含量的特殊砂土的力学特性；②结合技术规范的试验要求对固结试验方法中“固结压力”和“应变控制连续加荷”提出了见解；③针对北方地区含水率较小的非饱和土的特性，分析了土抗剪强度试验操作难和结果失真的原因。最后提出了几点有利于工程实际应用的建议

Abstract

As the basic method to obtain rock and soil’s physical-mechanical parameters

the soil test plays an important role in engineering design

construction and quality inspection. According to the experiences of doing experimental work over the years

the author offered their thoughts on a number of related issues. ①Taking the soil sample of a power plant in Tangshan for example

the mechanical properties of a special sand with certain clay in it

which is widely distributed in Hebei and Inner Mongolia are discussed. ②Combining with the test requirements in technical standards

some viewpoints on "the pressure of consolidation" and "continuous loading with strain control " in consolidation test

are put forward. ③For the characteristics of unsaturated soil with less water content in the northern region

the reasons why the soil shear strength test is difficult and the results are not exact

are analyzed. Finally

some advices in favor of practical applications in projects are proposed
