摘要
现场监测了山西省某高速公路隧道开挖过程的地表沉降数据,并将其与有限元计算分析的地表沉降数据作了对比,得到的数值计算结果与实测结果吻合良好,指出影响地表沉降的主要因素是围岩的力学参数和重力分布,为施工过程中需要采取加固的点提供了依据。
The paper undertakes the site inspection over the surface settlement in the excavation along some expressway tunnel in Shanxi province,has the comparison with the data from the surface settlement ones with the finite element analysis,concludes the consistency of the numeric calculation and the tested results,and points out the major factors affecting the surface settlement are the dynamic parameter and gravity distribution of the surrounding rocks,so as to provide some reference for the consolidation points in the construction.
