摘要:
以石家庄轨道交通3号线三教堂站多跨洞桩法施工为例，采用现场调研与数值模拟相结合的方法，研究了车站开挖过程中自身结构受力状态及对周围环境的影响规律，并提出适宜的控制技术。结果表明：采取措施后，地表沉降量在影响最大的两个阶段得到控制，同时管线累计沉降量减小，且车站主体结构受力状态得到较大改善，表明了控制技术的有效性。
Abstracts:
Relying on the multi-span pile-beam-arch (PBA) construction method at Sanjiaotang Station on Shijiazhuang rail transit Line 3, and combining field investigation and numerical simulation, the stress state of the station structure itself during excavation and the law of its impact on the surrounding environment are studied, appropriate control techniques are proposed. The research shows that after adopting the targeted measures, the surface settlement is controlled in the two most influential stages respectively, and the cumulative settlement of the pipeline is reduced, the stress state of the main station structure is greatly improved. All this verifies the effectiveness of the control technology.
