Standard test method for performing laboratory direct shear strength tests of rock specimens under constant normal force 在恒定的常规应力下进行岩石样品的实验室直接剪切强度试验的标准试验方法
The code snippets above cannot obviously be cut and pasted together to work , as this article is fairly liberal with the java syntax 上面的代码片段不能直接剪切并粘贴到一起，因为本文很不拘泥于java语法。
Standard test method for determining the internal and interface shear resistance of geosynthetic clay liner by the direct shear method 通过直接剪切方法对土工合成粘土衬里的内部和界面剪切抗性测定的标准试验方法

The direct shear tests indicate that the strength of the soils is affected obviously by the quantity of the water in the specimens . the dynamic triaxial tests show that the strength reduces and the pore water pressure increase with the rising of vibration times 在室内对土样进行了颗粒分析、渗透、直接剪切、振动三轴等试验；通过直剪试验成果，分析了斜坡土体的抗剪强度指标在不同含水量情况下的变化规律。
Secondly , in combination with basic physical experimentation of the henan item “ study on embankment settlement mechanism and development rule for highway in the silt soil region ” , the mechanics speciality of silty soil is completely cognized and realized , through the laboratory experimentation of three kind of classical silty soil in puyang city . the experimentation include laboratory physical mechanism test , static compaction test , direct shear test , permeability test . and also analysis the influence of water content on soil ’ s shear strength , permeability and other mechanism character 其次,结合河南项目“粉砂土地区高速公路路基沉降机理及其发展规律研究”课题的基本物理试验部分,通过对濮阳市三种典型的粉质土的室内物性力学性质试验、标准击实试验、直接剪切试验、渗透试验等一系列试验研究,对粉质土的各力学特性进行全面系统的认识和了解,分析了含水量对粉质土的抗剪强度、渗透性等力学性质的影响。
