摘要
结合杭州地铁5号线创意路站—蒋村站区间盾构法隧道投标方案,分析了斜交隧道施工过程中,上下侧隧道施工先后顺序对隧道结构受力的影响,阐述了斜交隧道施工过程中地表土体沉降的规律,论述了隧道间净距变化对隧道衬砌受力状态的影响,并通过对隧道周边加固体的数值模拟论证了注浆加固对隧道施工的效果。
Combining with shield tunnel tender scheme of Chuangyi station-Jiangcun station of Hangzhou subway line No. 5,the paper analyzes the impact of upper and lower tunnel construction procedure upon tunnel structure stress in inclined tunnel construction process,describes the surface soil subsidence law in inclined tunnel construction process,discusses the impact of tunnel distance change upon tunnel masonry stress, and finally discusses the effect of grouting reinforcement upon tunnel construction with numerical simulation of tunnel surrounding reinforcement.
