摘要
本文介绍了在老黏土地层中发现的软弱夹层这一现象,并总结分析了其分布特征、物理状态及其与老黏土的物理力学性质差异。通过工程实例,依据规范法及薄层挤压理论两种方法,对该软弱夹层的承载力进行了分析探讨。探究结果对老黏土场地的岩土勘察设计工作有着较重要的实践意义。
This paper introduces the phenomenon of weak interlayers found in old clay soil layers, and summarizes and analyzes their distribution characteristics, physical state, and differences in physical and mechanical properties from old clay soils. Through engineering cases, the bearing capacity of the weak interlayer is analyzed and explored according to two methods of the code method and the thin layer extrusion theory. It is of great practical significance to the geotechnical survey and design of old clay sites.
