盾构扩挖修建地铁车站对临近建筑物影响研究
|
摘要
现代城市的发展对地下工程施工的环境控制要求越来越高,特别是在地铁建设过程中,因此,在地铁施工过程中也越来越多的采用盾构施工,但是主要局限于区间隧道,由于车站与区间的差别,无法发挥盾构施工的优势。为了解决这一难题,发挥盾构的技术优势,提出了在盾构隧道的基础上扩挖修建地铁车站的施工方案。
本文就邻近建筑物工况下的盾构扩挖施工进行了分析与研究,内容包括：
(1)计算邻近建筑物工况下盾构扩挖施工引起的地面沉降及其在盾构推进阶段和上下台阶法扩挖阶段分别对土体的影响程度和在此过程之中邻近建筑物的内力变化趋势。
(2)针对建筑物在桩基础工况下,对邻近建筑物工况下的盾构施工进行了数值模拟分析。通过地面变形分析、建筑物受力分析来反映隧道、土体和建筑物三者之间的相互作用。
(3)隧道施工中应尽量减少对邻近建筑物的损坏,建立相关建筑物的评价标准。要对地面不均匀沉降、地面曲率以及地面水平变形进行严格控制,本文通过控制地面沉降来控制这三种地面变形量。
(4)对邻近建筑物施工的控制措施进行研究,参考相关的地表建筑物安全影响评估及其沉降控制标准,制定出对本工程有利的相关地表控制指标,同时结合实时监测数据,根据实际情况及时采取适当的工程措施以将盾构扩挖施工过程中对邻近建筑物的不利影响减到最小。
The environmental requirements on the construction of substructure are more and more strict in modern city, especially in the course of building metro tunnel. So more and more metro tunnels are constructed by shield tunneling machine, but it is limited in inter zone, for the difference of inter zone and metro station, the preponderance of shield tunneling can't be made full use of,for solving this problem, the construction schemes of metro station driven with enlarging shield tunnels were proposed.
This dissertation analyses and studies on the enlarging shield tunnel construction of adjacent structure and the main content of this dissertation as follows:
(1) Theoretical calculation and analysis of the soil settlement on the enlarging shield tunnel construction of adjacent structure; The different influence and the internal force change of the adjacent structure in the shield tunneling and the benching tunneling stage.
(2) Numerical simulation on the enlarging shield tunnel construction of adjacent structure which on the pile foundation.The interaction of the tunnel,soil and the adjacent structure can be reflect from the analysis of ground deformation and the force change in the adjacent structure.
(3) The evaluation standard of the structure can be established and to reduce the damage of the adjacent structure. The uneven settlement,Ground curvature and level deformation which are need to controlled strictly can be controlled from the ground settlement in this paper.
(4) To study about the construction control measures of the adjacent structure and to establish some favorable related ground control indexes about the engineering from the reference for the surface building security effect evaluation and the settlement control standard. Meanwhile, combining real-time monitoring data and the situation, to adopt the appropriate engineering measures in order to reduce the adverse effect in the adjacent structure on the enlarging shield tunnel construction as much as possible.
