桥梁桩基溶洞处置方案探讨

Research on the Karst Cave Treatment Methods of Bridge pile Foudation

岩溶地区地质条件复杂多变,对桥梁结构的安全、稳定有着极大的影响,是桥梁设计施工中的重难点,因此溶洞处置方案的研究具有重大意义。本文概述了溶洞处置的常用方法,详细介绍了注浆法和钢护筒跟进法两种处置方案,并对两种方案进行了对比。

The geological condition of karst area is complicated and has a great influence to the safety and stability of bridge and it is the key point of bridge design.So the research on the treatment of karst cave has great significance.This paper gives the overview of several usual methods to settle the karst cave and introduces slip casting method and steel casing following up method in detail,also,gives the comparison of these two methods.This paper could provide reference for the other similar projects.
