摘要:
以北京市某地铁隧道盾构工程为基础,研究了上覆雨污管线的稳定性和安全性。对比模型试验和有限元数值模拟,分析了隧道开挖引对管线的影响,研究结果显示:1)管隧平行时,开挖隧道引起的上覆雨污管线沉降基本呈现平缓分布。当l/D为1.5时,需在掌子面距盾构隧道尾部1.5D(D为盾构隧道直径)范围内加密监测点的布设,提高监测频率。2)管线顶部和底部应力分布呈平行趋势,当l/D为1.5时,需在沿管线分布范围内对管节进行抗拉防护措施。
Abstract:
On the basis of typical metro shield tunneling engineering, this paper studies stability and safety of rain and sewage pipeline. With the application of combine method of model test and numerical simulation, the deformation of pipeline and distribution of stress which is induced by the tunnel excavation are analyzed. As shown by calculation: (1) The uniform distribution can be presented in the settlement curve of pipeline when the pipeline and tunnel is parallel. When l/D is 1.5, the supervision points will be laid out densely and supervised frequently at the range of 1.5D between tunnel face and tunnel end. (2) The protective measures of tension and compression should be taken on the top and bottom of pipeline respectively.
