摘要
对白鳍豚大厦边坡滑移事故进行了分析,认为基坑周边水的渗漏是事故的主要原因。水土的作用,软化了土体,使土体的抗剪强度降低;水钉的作用,使土钉体外表面与土体界面接触粘结力与摩擦阻力显著降低。采用复合土钉支护技术处理边坡滑移是十分有效的措施,为类似的基坑支护和事故抢险提供了可借鉴的方法。
By analysis of slope sliding accident in BaiJi-tun Hotel, the accident was mainly caused by the seepage of water. Soil was soften by water. Shear strength was reduced. By action of water to nail, Bond between soil and nail a was obviously reduced, Composite soil-nail was effective measures to prevent slope sliding, it is beneficial to similar cases for quick rescue work and foundation pit bracing.
