盾构作为一种先进、可靠、方便的地下施工工具,如今已在众多工程中得到应用。盾构施工时,各类参数匹配与地而沉降之关系是一个较为复杂的问题,这不仅在于其本身的非线性、时效性以及多变量性,还在于各种因素的干扰,这些都导致了它们间各种关系的不确定性。 英国等国家早在20年代就开始重视对“在软弱地层中开挖隧道产生地面沉陷和地层变形”问题的研究,许多工程技术人员也为此进行了大量研究,并积累了不少由于盾构施工引起的地面沉降的控制方法。50年代以来,我国隧道专家在地铁、市政
Shield as an advanced, reliable and convenient underground construction tools, has now been applied in many projects. Shield construction, the relationship between various types of parameters and the settlement of the ground is a more complex issue, not only in its own non-linear, timeliness and multivariate nature, but also the interference of various factors, which led to the Uncertainty about the various relationships between them. As early as the 1920s, Britain and other countries began to pay attention to the research on the problem of “ground subsidence and formation deformation caused by excavation of tunnels in soft formations.” Many engineers and technicians also conducted extensive research to this end and accumulated a great deal of achievements due to the fact that shield Construction control caused by ground subsidence. Since the 1950s, China’s tunnel experts in the subway, municipal
