摘　　要：西久公路是青海省南部的一条重要省道公路,是青海省果洛藏族自治州通往省会西宁的唯一通道。本文针对西久公路K359处军功镇山体滑坡原治理方案采用渗水隧道方式处理地下水遇到的施工风险大、进度缓慢等问题,从安全、进度、经济等各方面比选渗水隧道与辐射井两种不同方式控制滑坡体内地下水的效果,并通过实践检验了辐射井结合水平井技术治理地质灾害的效果。应用辐射井技术大大提高了施工效率,同时确保了滑坡体安全、节省了工程投资并减少了公路隐患,具有现实的工程指导意义,为公路边坡治理工程提供了相关依据。The Xijiu Highway is an important provincial road in Qinghai Province, which is the only access from Guoluo Tibetan Autonomous Prefecture to Xining City. The original treatment scheme is oozing water tunnel disposing groundwater to renovate the landside of Xijiu Highway K359 in Jungong Town. But it has the problem of construction risk and slow progress. By comparing the oozing water tunnel with the radial well technology to renovate the landside, the radial well technology combined the horizontal well technology is better to renovate the geological disasters. Practice has proved that the application of radial well technology has greatly increased the construction efficiency. At the same time it can ensure the landside safety. And it also can save the project investment and reduce the hidden trouble. The radial well technology has the realistic significance to engineering, and provides the related basis for highway slope treatment proiect.
