浅谈岩土工程勘察中钻探工艺的选取

摘要

在岩土工程勘察过程中,由于土层的性质不同,在实施工程地质钻探时所采取的工艺措施也不一样。通过对软弱粘性土、硬粘性土、砂及卵（碎）石的钻探工艺实践,在钻进方法的选择、钻具的选择方面进行了总结。%In the process of geotechnical engineering investigation,because of the nature of the different soil,in the implementation of engineering geological drilling are taken process measures is not the same.Based on the soft clay,hard clay,sand and egg（broken） stone drilling technology practice,in the drilling method and tool selection is summarized.
