Method for calculating reasonable burial depth of subsea tunnel
The invention provides a method for calculating the reasonable burial depth of a subsea tunnel, and belongs to the technical field of design and construction of subsea tunnels and underground engineering, and the method comprises the following steps: 1, obtaining physical and mechanical parameters of rock strata of a proposed tunnel from top to bottom through investigation data; step 2, obtaining information of a tunnel to be built through a tunnel design scheme; (4) establishing a stratigraphic structure numerical model by taking a seawater load, physical and mechanical parameters of rock strata from top to bottom of a proposed tunnel and the like as input conditions, simulating redistribution which is influenced by a tunnel excavation effect and generated by surrounding rock stress, and obtaining a height value HS of the overlying rock strata disturbed by an excavation and support process according to a simulation result; and 5, calculating the final minimum covering layer thickness of the subsea tunnel. According to the method, a top water coal mining method is combined with numerical simulation, the reasonable burial depth of the subsea tunnel is obtained, the influence of the tunnel supporting effect on the burial depth of the tunnel is considered, and the deformation mechanism of tunnel excavation supporting is met.
本发明提供了一种海底隧道合理埋深的计算方法，属于海底隧道与地下工程设计与施工技术领域，包括以下步骤：步骤1：通过调查勘察资料，得出拟建隧道自上而下岩层物理力学参数；步骤2：通过隧道设计方案，得出拟建隧道信息；步骤3：计算隧道最小覆盖层厚度，步骤4：将海水荷载、拟建隧道自上而下岩层物理力学参数等作为输入条件，建立地层结构数值模型，模拟受隧道开挖作用影响，围岩应力产生的重分布，根据模拟结果，得出上覆岩层受开挖支护过程扰动的高度值HS；步骤5：计算最终的海底隧道最小覆盖层厚度。本发明将顶水采煤法与数值模拟结合，得出海底隧道合理埋深，考虑了隧道支护作用对隧道埋深的影响，符合隧道开挖支护的变形机理。
