Analysis of the Shear Stress on Prestressed Anchor in Rock Mass

Abstract

The shear stress of prestressed anchor cable is unevenly distributed along anchoring length.Based on the load transfer behaviors of bolt,the solutions for distribution of the shear stress in pre-stressed cables are derived.And the mechanical characteristics are discussed for the influences on the shear stress distribution.The calculated values are compared with the results of the filed tests,and good agreements are obtained.

The Numericial Calculation of Retaining Structure with Double-Piles

“…It is widely used by lots of people in the project for its advantages in controlling displacement, convenient construction and saving underground space [1]. But there is some disadvantages limit its use, such as the stress of the structure is too complicated to get a relatively perfect calculation theory, many areas limit the use of the anchor cable [2]. So the theoretical research of the double-row piles is far behind the engineering application.…”
