黄河小浪底坝区泥化夹层分布及其抗剪试验方法的分析

DISTRIBUTION OF THE CLAY INTERCALATION IN THE XIAOLANGDI DAM AND EXPERIMENTAL METHOD OF SHEAR STRENGTH

在大量地质勘探试验研究资料的基础上 ,分析研究了形成泥化夹层的母岩和地质构造力 ,泥化夹层的类型及其粒度成分以及泥化夹层的分布规律。还分析研究了不同试验方法对泥化夹层抗剪强度的影响 ,并着重分析研究了我院研制的控制膨胀饱和固结慢剪的试验成果。

Based on the large amount of data from geology exploration and test and research results, parent rocks of clay intercalation and tectonic force which caused the clay intercalation to formed are studied. Classification, granularity, and distribution of the clay intercalation are also studied. Furthermore, effect of different test methods on shear strength is studied. Then the results of slow shear test on controlled dilated saturated consolidated specimens developed by our institute is analyzed.
