situ soil test

Research shows that in-situ test methods reflect the engineering properties of the soil more objectively and serve the survey and design of the excavation engineering better.

研究表明：原位测试方法能更客观的反映土体工程性质，更好的为基坑工程勘察、设计服务。

Taking the expensive soil in Nanyang Area, Henan Province, as study case, the in-situ shear test method, including preparing samples and test method, is proposed in the paper.

结合南阳地区膨胀土的抗剪强度研究，对其现场剪切试验的试样制备及试验方法进行探讨，提出了膨胀土抗剪强度的修改计算公式。

It is therefore easy to conclude that the swelling soil ground is a semi-infinite space and it is feasible to adopt the lateral restriction test of in situ swelling soil.

结论膨胀土路基为半无限体空间体，采取有侧限的原位膨胀力试验是合理可行的。
