土层锚杆加固建筑物的设计应用

Design and Application of Ground Anchor in Strengthening Structure

本文结合大禹渡沉沙池池堤加固，重点介绍土层锚杆加固永久建筑物设计中，支护形式、锚杆布置方式、锚杆承载力计算、锚杆体设计及锚固设计的方法，对土层锚杆技术在水利工程建设中推广应用有一定的意义。

In strengthening works of the slope of side wall of silt basin,Dayudu pumping station,the ground anchor was used.Some issues concerning the design of the ground anchor are introduced in this paper:the layout of the ground anchor,determination of the bearing capacity of the ground anchor,determination of the diameter of drill hole of the ground anchor,determination of the shear strength of soil around anchorage section,determination of the ground anchor length,anchor rod,anchor grouting and so on.The ground anchor is regarded as being significant for water project.
