摘要
猴子石滑坡续建治理工程首次采用了地下置换阻滑键结构措施,其体型复杂,布置明确。结构实施的关键技术主要包括结构布置方式、关键施工技术、关键构造措施和效果监测措施4方面。结构布置方式遵循动态设计、信息化施工的实施原则、追踪滑带确定洞井的定位方法、分级平行施工,由平洞至竖井的开挖程序和不同洞井的功能分类;关键施工技术主要体现于维护施工期洞室稳定、保护围岩完整性和保证结构混凝土回填质量;关键构造措施主要体现于钢筋套管连接工艺、快速承力锚杆和洞顶回填灌浆;效果监测措施主要包括滑坡体变形监测、结构受力状态监测和地下渗流监测。
Underground replacement-retaining structure is first used in Houzishi landslide control with complex shape and explicit arrangement.The key technical factors of structure application include structural arrangement way,key construction technique,key constructional measures and effect monitoring measures.The structural arrangement way follows the implementation principle of dynamic design and informational construction,the localization method of arranging adits and shafts by tracing slippery belt,the excavation procedure of layered parallel construction,and the function classification of different adits and shafts.The key construction technique mainly manifests in maintaining cavern stability,protecting surrounding rock integrity and guaranteeing structural concrete backfill quality.The key constructional measures mainly manifest in rebar mechanical splicing,quick-acting anchor and backfill grouting of roof.The effect monitoring mainly include landslide deformation,structure stress and underground seepage.
