随着盾构法地铁隧道施工的普及,盾构同步注浆在施工中扮演着越来越重要的角色,同步注浆效果的好坏直接影响到地面及建筑物的稳定。本研究在总结武汉地铁六号线第三标段江城大道站至老关村站区间同步注浆调控经验的基础上,提出使用p-q法评价壁后注浆效果及浆液固结形态,总结出一套同步注浆调控程序,从而能够更加方便更加准确更加快捷的调节注浆的操作参数,严格控制地面沉降变形。
With the popularization of shield tunneling construction, synchronous shield grouting plays an increasingly important role in construction. The effect of synchronous grouting directly affects the stability of the ground and buildings. In this paper, on the basis of summarizing the synchronous grouting control experience of Jiangcheng Avenue Station to Laoguancun Station in the third section of Wuhan Metro Line 6, the pq method was used to evaluate the grouting effect and the consolidation form of slurry, Set of synchronous grouting control procedures, which can be more convenient and more accurate and more efficient adjustment grouting operating parameters, strict control of land subsidence deformation.
