摘要

结合深圳地铁大剧院—科学馆区间隧道非降水施工对管线的影响问题，阐明了该工程的施工方案，给出了管线安全性的评价标准。在此基础上，首先利用土工离心模型试验，模拟了隧道开挖对管线的影响，然后，利用三维弹塑性有限元法模拟了隧道施工过程中管线的动态响应。通过离心模型试验、数值模拟分析、现场量测的地表沉降值的对比分析可知，三者的数据基本吻合，论证了分析结果的合理性和可靠性，并对施工期间管线的安全性做出了评价，为该工程顺利实施提供了理论依据和指导作用，并取得了一些有意义的成果。

Abstract

Combined with the practical engineering problem of Dajuyuan-Kexueguan interval tunnel excavation of Shenzhen metro by non-water lowering with adjacent pipeline

the construction scheme is illustrated; and evaluation standards of buried pipelines are given. Firstly

the effect of interval tunnel excavation on the buried pipelines is simulated by means of centrifugal model test. Secondly

the 3-D FEM coupling analysis model of tunnel supporting-soil-underground pipeline is established. Deformation and internal force of buried pipeline are analyzed specially by numerical simulation of tunnel excavation and also the safety of the pipeline is forecasted. The rationality and reliability are proved by comparing the results of centrifugal model test

numerical simulation and in-site measurement. Theoretical base and guidance are provided for real engineerings and some meaningful results are achieved.
