盾构隧道同步注浆的压力分布及其影响因素
Journal of Shenzhen University Science and Engineering(2015)
Abstract
结合城市地铁盾构法隧道工程实际,以盾尾同步注浆浆液环向填充过程为研究对象,选取环向任意一点建立注浆压力力学模型。假设浆液符合宾汉姆流体,应用流体力学与极限平衡法的基本原理,推导盾构壁后同步注浆环向填充压力分布统一计算模型,并将此模型推广到多孔注浆情形。工程实例分析表明,推导的盾构同步注浆压力分布统一模型合理;小径盾构隧道宜采用四孔注浆,大径盾构隧道宜采用六孔或多孔注浆方式;注浆孔位置、盾尾间隙和截面流量对浆液压力分布有重要影响,应在盾构施工中予以重视。
