广西地区岩溶分布广泛,溶腔具有隐伏发育分布不规律且多呈串珠状分部、腔体体积较大、地下水系发达等特点。本文针对深桩基施工难点,介绍分析施工过程中不利影响的成因,同时在传统岩溶处理工艺工法的基础上,对深桩基施工中护筒跟进、溶腔封堵、水下爆破等岩溶处理工艺进行了研究创新。 Karst is widely distributed in Guangxi. The karst cave has the characteristics of hidden development and irregular distribution, many beaded branches, larger cavity volume and developed underground water system. In this paper, according to the difficulties in the construction of deep pile foundation, the causes of adverse effects during the construction process are introduced. On the basis of the traditional karst treatment method, the following problems are solved: the casing follow-up, cavity sealing and underwater explosion karst Processing technology research and innovation.
