静探工作日前在全国还没有一个统一的型式和规程,特别是探头的形状还各有差异,如何把这一工作渐趋一致和统一,尚待有关单位积累对比资料和总结。现就我们在静探工作中发现的几个问题阐述如下: 1.关于贯入速率 贯入速率对比贯入阻力的影响问题,国内外都做过很多研究和试验,证明在静力贯入中,速率的影响是很小的,一般在可塑状粘性土层中速率增加三倍时,Ps值增加8
There has not been a unified pattern and procedure in the country before the static exploration work day. In particular, the shape of the probe is still different. How to make this work more consistent and unified, and the relevant units have yet to accumulate comparative data and summary. Here are some of the issues that we have discovered in our work on static exploration: 1. On the impact of penetration rate penetration rate versus penetration resistance, many studies and experiments have been conducted both at home and abroad to prove that static penetration The effect of velocity is very small. Generally, the Ps value increases by 8 when the rate increases three times in the plastic clay layer.
