土体颗粒破碎研究进展

Advance in studies of soil grain crush

在打入桩的桩端以及大型土石坝、海洋平台等的地基中常常会出现高应力区。在这些高应力区中,作为地基的粒状土的颗粒会发生不同程度的破碎。对高应力水平下粒状土体的破碎特性进行深入研究有助于解决这一类型的岩土工程问题。因此近年来土体颗粒破碎逐渐引起人们的重视。本文对土体颗粒破碎研究现状进行了详尽的阐述,并指出研究中存在的问题及今后研究发展方向。

Many geotechnical engineerings are constructed accompanied by the occurrence of high stresses, such as pile end bearing high earth or rockfill dams or foundations of offshore gravity structures. Such high stresses would lead to the crushing of even the strongest soil particles. Understanding the behavior of soils subjected to high pressures is fundamental to assisting in the solution to these types of geotechnical engineering and geological problems. So the problem of soil grain crush attracts more and more interests of man. This present paper elucidates in detail the current condition of studies on this problem and points out the problem and the direction in coming studies.
