摘要
某铁路车站站内一段路堤,原采用碎石桩加固基底。施工过程中突发坍塌病害,严重影响了施工进度。结合工程介绍了该病害的发生和发展情况,详细分析了病害产生的原因。采用水泥搅拌桩联合反压护道对路基坍塌进行治理,实践证明,路基安全稳定。
A section of embankment in a railway station adopts gravel piles to reinforce the foundation, which collapsed suddenly during construction, affecting the construction period seriously. This paper introduced the occurrence and development of this disease and analyzed the causes in details. Cement mixing pile combined with back berm was adopted for treatment. Then the practice has proved that the subgrade is safe and stable.
