摘要：采用 FLAC3 D软件 ,以拟建的广州地铁 3# 线典型车站为例 ,对盾构过站 ,扩挖成站施工引起的地表沉降规律进行了数值模拟 ,研究了不同工况盾构双隧道过站施工对地面带来的影响 ;并在此基础上采取不同加固土体措施情况下 ,模拟了扩挖建站对地面变形的影响程度 .研究结果对盾构直接过站方案是一种技术支持 ,作为盾构过站施工对地表沉降影响预测的方法 ,可为我国盾构法技术的扩大应用提供部分理论依据和参考 .

摘要：The whole depth measuring plan and its implementation method of surrounding rock mass pressure on the wall′s of a shafts are described, which is in Suncun Coal Mine with a depth of 1 000 *** with the combination of data processing, it is discussed the effects of such factors on the distribution law of shaft surrounding rock pressures as rock quality,burying depth, end effect due to excavating, rock stratum dip, shaft wall structure form and regression formulae relating to the shafts surrounding rock pressures as well as to several other *** finally, the measured results were verified according to the comparison between analyses of stress strain of side walls and side wall strain measurements.

摘要：盾构法隧道是当今基础建设中应用广泛的施工方法，而传统盾构法隧道因其面临着诸多工程技术难点和社会问题，急需升级新方法、新技术。本项目针对超浅覆土、负覆土盾构隧道“失稳、失衡、失效、失准”四大国际性难题，围绕该新技术的可行性，可靠性、可掘性及可控性目标，创新建立了“地面出入式盾构法隧道技术体系”。
