| 摘 要： | 在锚固工程成孔中，软土含砾地层成孔困难，钻进效率低，效率效益差，针对这种情况分析了地层特点和采用不同成孔方法施工存在的问题，找出了一种比较适应的钻进成孔方法，并通过生产实践证明效果较佳，为软土含砾地层倾斜孔成孔提供了一种新方法。

| Abstract: | The well completion with anchoring is difficult in pebbly soft clay formation for low rate of penetration and high cost.A more convenient drilling method is found by comparing the various drilling methods in the special clay formation and analysing the formation character.This drilling method,which was proved by field practice,is a new one and has high penetrating rate for the incline of hole drilling in the pebbly soft clay formation. |
