预加固技术在高速公路边坡中的应用

摘要

Pre-reinforcement technology is a new technology that has been widely applied in geotechnical engineering in recent years.Taking Baini＇ ao landslide control project in Yongzhou-Lanshan Highway for example,the failure mode of high slope is described in this paper.Thus the principle and applicable condition of slope pre-reinforcement technology are introduced,and its construction process,construction steps and economic benefit are explained,which provides reference for slope disaster prevention in highway engineering.%预加固技术是近年来广泛应用于岩土工程的一项新技术。以永蓝高速公路白泥坳滑坡治理工程为例,简述高速公路高边坡变形破坏模式,介绍边坡预加固技术的原理及适用条件,并阐述其施工工艺、施工步骤及技术经济效益,为高速公路中边坡灾害防治提供参考。
