| 摘 要： | 地铁盾构隧道穿越岩溶填充区受力情况复杂,为保证施工安全和管片受力合理,采用有限差分程序建立数值计算模型,通过计算分析获得盾构穿越地层的受力情况。盾构隧道穿越岩溶填充区时虽然会产生一定的地表沉降,但在安全范围之内,管片受力也是合理的。

| Abstract: | Internal force of the subway shield tunnel which thru the karst-filling area is complicated.In order to make the construction safe and the force of shield segments reasonable,we have used FDM model to establish numerical calculus model and get the internal force of the shield tunnel thru different stratum.Although some ground surface settlement will be caused when through karst-filling area,it is in the safe range,and the internal force of the shield tunnel is also reasonable. |
