摘要
重点研究了在青藏高原多年冻土区进行钻孔灌注桩施工时所遇到的问题,从多年冻土的本身特性以及钻孔灌注桩施工后可能对多年冻土所产生的扰动和影响,对比了国内外相关多年冻土区进行钻孔桩施工时的资料,结合五道梁中桥钻孔桩施工的工程实例,研究了在青藏高原多年冻土区进行钻孔桩施工时的行之有效的方法,进而分析了青藏铁路钻孔灌注桩施工中如何进行质量控制所要注意的问题,并相应提出了解决措施。
The paper makes an intensive study of the problems in the construction of bored piles in frozen soil of the Qinghai-Tibet Railway. After analyzing the characteristics of frozen soil and the possible effects on and disturbance to the frozen soil after the construction of bored piles, and comparing all the information about the construction of bored piles in frozen soil both at home and abroad, with the construction of bored piles in frozen soil for the medium bridge at Wudaoliang as an practical example taken into consideration, the paper studies the effective methods for the construction of bored piles in frozen soil and further analyzes the problems which have to be paid attention to in the practice of construction quality control ,with corresponding effective solutions to the problems suggested.
