【摘要】：研究目的:昆明南连接线高速公路工程五标段在即将交付验收前,一段路基地段出现两处较为严重的滑坡险情,其中一处已经完全滑塌,另一处处于滑溃前的极限状态。本文通过工程案例的现场调查分析及整治处理,试图找到一种能够早期预测工程滑坡隐情并减少甚至避免工程滑坡灾害发生的方法途经,为今后公路、铁路、地铁、水库大坝等工程中类似边坡工程问题的处理提供借鉴。研究结论:(1)现有两处滑坡的性质、状态截然不同,其中K 23+475~550段属于彻底滑溃的浅层顺层岩质滑坡,已基本稳定,K 23+680~800段属于深层牵引式土质滑坡,处于滑溃前蠕变阶段,状态极不稳定;(2)利用综合地质分析法分析预判出,K 23+550~680段边坡属于潜在的浅层顺层岩质滑坡,存在滑塌的极大可能;(3)根据滑坡各自的性质特征,提出了不同的整治方案,依次分别是:彻底清除、预加固、应急抗滑与永久抗滑;(4)本文提出的综合地质分析法可为类似边坡工程的灾害预判、应急抢险、永久整治提供借鉴。
[Abstract]:Research objective: before the fifth section of Kunming South Link Expressway Project is about to be accepted, two more serious landslide hazards appear in one section of the road base, one of which has completely collapsed and the other is in the limit state before the collapse.Based on the field investigation and treatment of engineering cases, this paper tries to find a way to predict the hidden situation of engineering landslide early and to reduce or even avoid the occurrence of engineering landslide disaster, for the future highway, railway, subway,The treatment of similar slope engineering problems in reservoir dam and other projects can be used for reference.Conclusion: (1) the characteristics of the two landslides are quite different. Among them, K23 475U 550 belongs to the shallow bedding rock landslide, which is basically stable and belongs to the deep traction type soil landslide, and is in the creep stage before the collapse.In this paper, the authors prejudge that the slope of section K23 550 is a potential shallow bedding rock landslide, and that there is a great possibility of landslide collapse. According to the characteristics of the landslide, different regulation schemes are put forward.4) the comprehensive geological analysis method proposed in this paper can be used as a reference for the disaster prediction, emergency rescue and permanent treatment of similar slope engineering.
