Reinforcing method for water-rich fine sand miscellaneous fill stratum and over-crossing subway tunnel
The invention discloses a reinforcing method for a water-rich fine-sand miscellaneous fill stratum and an over-crossing subway tunnel, which is used for a construction environment of the water-rich fine-sand miscellaneous fill stratum and the over-crossing subway tunnel, and comprises the following steps of: 1, performing finite element simulation on a reinforcing working condition of a project by adopting MIDAS-GTS NX, firstly simulating a reinforcing construction process, and then simulating a reinforcing construction process by adopting MIDAS-GTS NX; pre-judging the deformation of the subway project; 2, calculating parameters and assuming, and assuming that an interval lining segment material is a linear elastic material; mIDAS-GTS NX is adopted for conducting finite element simulation on the reinforcement working condition of the project, MJS pile testing is conducted, and a reasonable MJS reinforcement pile and upheaval-resistant pile construction method, a measurement robot subway monitoring technology and the like are researched and formulated. According to the method for determining MJS construction parameters of different stratums, construction of MJS reinforcing piles and anti-upheaval piles is conducted in the mode that the middle and the two sides are sequentially conducted, deep and shallow are sequentially conducted, and the two sides and the upper portion of a subway are sequentially constructed, adverse effects of construction on subway segments and surrounding buildings are reduced, and subway deformation is within the controllable range.
本发明公开了一种用于富水细砂杂填土层且上跨地铁隧道的加固方法，其使用于富水细砂杂填土层且上跨地铁隧道的施工环境，包括以下步骤：步骤1：采用MIDAS‑GTS NX对本工程加固工况进行有限元模拟，首先模拟加固施做过程，对地铁工程的变形进行预判；步骤2：计算参数与假定，假定区间衬砌管片材料为线弹性材料；本发明通过采用MIDAS‑GTS NX对本工程加固工况进行有限元模拟、MJS试桩、研究制定合理的MJS加固桩及抗隆起桩施工方法、测量机器人地铁监测技术等。确定不同地层MJS施工参数、MJS加固桩、抗隆起桩施工“先中间后两侧，先深后浅，先施工地铁两侧后上方”的方法，减少施工对地铁管片及周边建筑物带来的不利影响，使地铁变形在可控范围内。
