高速铁路客运专线施工主体为混凝土结构工程,结构工程基础施工主要为钻孔灌注桩,而钻孔灌注桩作为一种深基础型式,以其适应性强、承载力大、施工较为简单被广泛应用。哈大铁路客运专线钻孔桩数量较大,地质条件跨度较大,钻孔桩事故时有发生,因此本文主要针对钻孔桩事故原因进行分析,并提出相应预防和补救措施。
The main construction of high-speed railway passenger dedicated line for the concrete structure engineering, structural engineering foundation construction mainly for bored piles, and bored piles as a deep foundation type, with its adaptability, bearing capacity, construction is simple and is widely used . The number of bored piles in Harbin-Dalian Railway Passenger Dedicated Line is large, the span of geological conditions is large, and the accidents of bored piles occur from time to time. Therefore, this paper mainly analyzes the causes of bored pile accidents and puts forward the corresponding prevention and remedial measures.
