原位测试求取岩土参数应用总结

A Summary of Obtain Several Geotechnical Parameters Through In-situ Tests

相对于钻探、取样、室内实验等传统方法,原位测试具有明显的优点,其涉及的土体比实验室样品大得多,测试技术方法可连续进行,可以得到完整的土层剖面及物理力学性质指标,周边土体中的应力未释放,因而更能反映土体的宏观结构对土的性质的影响,能够获得接近实际的试验结果。本文通过不同原位测试方法求取几个岩土参数方法的总结,对工程勘察过程原位测试的应用具有一定的借鉴作用。

Compared with traditional methods of drilling, sampling,laboratory experiments, in-situ tests has obvious advantages. In-situ tests samples involves more than laboratory, testing methods can be continued, you can get full soil profile and physical properties, not release of stresses in surrounding soil mass, and thus more able to reflect the macro structure of soil influence on the soil properties, get close to the actual test results. A summary of obtain several geotechni- cal parameters method, reference of the the engineering investigation process in-situ tests applications.
