预应力自由锚索对深埋地下洞室的加固效果

Prestressed Cable Anchors and Its Reinforcing Effects on Deep-Buried Caverns

本文简要介绍了预应力自由锚索的结构特点和受力特征,通过工程实例介绍了预应力自由锚索对软岩中深埋地下洞室的作用效果,提出了预应力自由锚索加固深埋地下洞室的一般原则。

Constructional and load-carrying characteristics of prestressed cable anchors is introduced. Based on a historical case, reinforcing effects of prestressed cable anchors on deep-buried caverns in soft rock-mass is presented. Finally, the general principles of reinforcement of the deep-buried caverns by prestressed cable anchors were derived.
