双线盾构隧道下穿对输水暗涵影响的数值分析
Numerical Analysis of Twin Shield Tunnels under-crossing Influence on Buried Culvert
摘要
Abstract
For studying the influence of the twin shield tunnel under⁃crossing on the buried culverts and offering the suitable reinforcement method, based on the real project construction parameters, the FLAC3D was adopted to nu⁃merically simulate the effects of unreinforced, only stratum surrounding culverts reinforced, only stratum around tunnels reinforced, and both strata around culverts and tunnels reinforced on buried culvert, and the results of numerical simu⁃lation were compared and analyzed. It was induced by above⁃mentioned methods respectively that the largest vertical deformation of buried culvert is 26.3 mm,14.5 mm,12.7 mm and 6.8 mm, there was obvious stress concentration exi⁃ting on the culvert sections for the unreinforced method, there were the plastic zones appearing on the culvert deforma⁃tion joints for the former two methods, and there were not plastic zones appearing on the culvert deformation joints for the latter two reinforced methods. The last improvement method was very effective for reducing the deformation of cul⁃vert structures and surface subsidence.关键词
