摘要
静力触探是一种轻便、快速、高效的土的原位测试技术。结合国内外静力触探技术的研究应用情况,介绍了静力触探技术在岩土工程勘察中划分土层界面、土类定名、确定地基承载力和单桩极限承载力、判定地基土液化可能性及测定地基土的物理力学参数等的应用。通过实际工程案例介绍了孔压静力触探技术的应用情况,在国内岩土工程勘察中应大力推广孔压静力触探技术。
Cone penetration test is a portable-fast-efficient in situ test technique.Based on the domestic and foreign study and application of cone penetration test technique,the CPT technique can be applied to classify the soil layer and soils properties,determine the load-bearing capacity of ground,estimate ultimate bearing capacity of a single pile,evaluate liquefaction of sandy soils and evaluate physico-mechanical properties of soils in geotechnical investigation.Combined with the application of piezocone penetration test in actual project,piezocone penetration test should be energetically spreaded in China.
