摘要
广西南宁市城区内的某深厚人工堆填土滑坡,由于滑坡体物质组成特殊及土方外运困难,传统的抗滑桩支挡、挖方卸载措施均无法做到有效、经济地治理,文章采用"削坡减载(放坡)+水泥搅拌桩支挡+坡面格构+坡面截排水沟及护脚挡墙+坡面绿化"的综合防治措施,达到了"坡体稳定、尽量减少土方外运和经济合理"的治理目标,而其中的"水泥搅拌桩支挡"方法则开了对这类滑坡防治的先例,为今后对这类滑坡防治积累了宝贵的经验。
For the landslide of a deep and thick artificial landfill in the urban area of Nanning, Guangxi, due to the special composition of landslide material and the difficulty of outward earth transportation, the traditional anti-slide pile support and the excavation unloading measures can not achieve the ef- fective and economical treatment.Thus this article adopted the comprehensive prevention and control measure of＇s4ope reduction and load raducing（grading）＋ cement mixing pile support＋ slope grid structure＋ slope surface intercepting drains and slope-toe retaining wall＋ slope surface greening＂to achieve the treatment goal of＂slope stability, reducing the outward transportation as far as possible, and economic rationality＂ ,of which the＂cement mixing pile support＂method is the precedent for the treatment of such landslides, thereby accumulating the valuable experience for the future treatment of such landslide.
