钢管桩与预应力锚索在公路路堑高陡边坡中的综合应用

The Application of Steel Pipe Stake and Prestressed Anchor Rope in the Construction of Steep and High Slope of Highway Cut

本文通过介绍镇水公路K62+374—K62+500段路堑右上边坡坡口线拦渣墙失稳的岩土工程条件,解析治理方案选用的理论依据,通过理论计算分析,根据实际情况采用钢管桩与预应力锚索、喷射水泥砂浆封闭坡面等综合性工程治理措施。

This article introduced engineering geological conditions about block dregs wall at right slope cut in Zhenshui highway k62 ＋ 374 - k62 ＋ 500 part, analyzedtheoretical basis of applying for practical improvement plan. Through theoretical calculation and physical reality, improving measures like steel pipe stake and prestressed anchor rope were adopted, and cement plaster injection was undertaken to close slope.
