简要介绍该工程两岸高边坡十分复杂的地质构造与其塌滑体的治理 ,对左岸大片碎石土堆积物形成的古滑坡体的整治 ,采用大型沉井群施工方案 ,这在国内是首创 ,国际上也是不多见的 ;对右岸的滑坡体处理 ,采用锚洞群和预应力锚索联合作用的施工方案 ,施工中攻克许多技术难题 ,在技术与经济上都取得满意的效果。这些施工治理措施的设计优化方案是成功的 ,设计与施工都取得许多宝贵的经验 ,类似该工程地质的治理可资借鉴。
This paper briefly introduces the complicated geological structure of the high slope on both sides of the project and the harnessing of the landslide bodies. The improvement of the ancient landslide body formed by the massive debris on the left bank adopts the construction plan of large sinkhole group, which is the first in China. It is also rare in the world. For the landslide treatment on the right bank, the construction scheme using the combined action of anchor hole groups and prestressed anchor cables has overcome many technical problems in construction and has achieved satisfactory results both technically and economically. The design and optimization schemes of these construction measures are successful. Many valuable experiences have been gained in design and construction, which are similar to the engineering geological treatment.
