对山立交路堑高边坡设计及稳定性分析

Design of High Side Slope for Road Moat in Duishan Interchange and Analysis of Stability

对山立交路堑高边坡高达60m,坡顶有高压铁塔两座,边坡岩体类型为III类。如何在满足电力法规的情况下,保证高压铁塔及边坡岩体稳定,是工程设计的重点与难点。该文利用数值方法分析其边坡的应力状态和岩体强度,综合评价了该高边坡的稳定性。

The high side slope for the road moat in Duishan Interchange is 60 m high. There are two high-voltage iron towers at the top of slope. The rock type of side slope is Class III. How to guarantee the stabilization of the high-voltage iron tower and the side slope rock under the condition to meet the electrical code is the keystone and difficulty of the engineering design. The article utilizes the numerical value method to analyze the stress status and the rock strength of its side slope, and comprehensively evaluates the stability of this high side slope.
