软弱富水地层浅埋暗挖隧道地表沉降和支护结构受力的模型试验
|
摘要
以莞惠城际轨道交通工程项目GZH-5标段中DK32+300~DK32+927.303段为背景,通过2组模型试验,其中一组无超前注浆,另一组进行超前注浆,研究软弱富水地层浅埋暗挖隧道地表沉降和支护结构受力规律及超前注浆对其受力变形造成的影响,最后,针对软弱富水地层浅埋暗挖隧道施工,提出几点隧道工程设计和施工的相关建议。
This paper focuses on the rail transit of DK32 + 300 to DK32 + 927.303 in GZH-5 contract section between Dongguan and Huizhou to study the ground settlement and stress of the support structure of the shallow excavated tunnel in weak water-rich layer and the influence of advanced grouting on the settlement and stress by means of model tests in two groups:one with advance grouting,the other without.Finally,some construction suggestions are put forward for the shallow excavated tunnel in weak water-rich layer.
