盾构隧道壁后注浆试验的研究现状与发展
|
摘要
针对盾构隧道壁后注浆室内试验装置设计及相关测试的问题,总结了目前国内外已开展的壁后注浆室内试验装置的主要特征以及所进行的相关测试。根据室内试验的研究对象将其分为整体模型试验、局部模型试验。整体模型试验以实际工程为原型,通过模拟盾构施工过程,分析壁后注浆对管片和地层的受力、变形的影响以及浆液的扩散特征。局部模型试验以隧道周边局部地层为原型,通过建立盾尾间隙、注浆体、地层土体三元素的浆液扩散试验装置,研究注浆体压力消散、固结的机理。通过总结壁后注浆室内模型试验,为其今后研究工作的开展提供参考。
Aiming at the design of laboratory grouting test device for shield tunnels and related testing problems,the main characteristics of the backfill grouting laboratory test device and the related tests carried out at home and abroad was summarized.According to the research object of the laboratory test,it was divided into an overall model test and a partial model test.The overall model test was based on the actual engineering.Through the simulation of the shield construction process,the influence of backfill grouting on the force and deformation of the segment and the formation and the diffusion characteristics of the slurry were analyzed.The partial model test was based on the local stratum around the tunnel.The mechanism of dissipating and consolidating the grouting pressure was studied by establishing a slurry diffusion test device with three elements of shield tail gap,grouting body and stratum soil.Through the summary of the model test of the backfill grouting chamber,it has certain reference value for the development of the backfill grouting test.
