| 摘 要： | 针对西安地铁2号线盾构施工下穿古城墙问题,在考虑城墙损伤的前提下,采用三维弹塑性有限差分法FLAC 3D软件模拟了不同加固措施工况下盾构施工对西安城墙北门的影响,得出了盾构掘进过程中城墙的沉降规律,并对该规律进行了分析.研究结果表明,采取钻孔灌注桩及化学注浆复合加固措施可以有效地保证城墙安全,为西安地铁2号线的施工及保护古城墙提供了指导性的建议,并为日后有关黄土地区的盾构施工提供了参考.

| Abstract: | To the problem of shield tunneling of Line 2 of Xi'an Metro under the ancient wall,the effects of shield tunneling on the northern door of the wall are simulated with different kinds of reinforcements through the software of FLAC 3D,and the damage to the wall is considered.The law of the city wall's settlement is obtained.Through the analysis to the law,the reinforcement method by using both the cast-in-place pile and the chemical injection can make the wall safe enough.The guiding suggestion to the line 2 ... |
