徐家汇藏书搂是闻名于国内外的古建筑,位于徐家汇地铁车站西侧,初步预测,地铁车站的施工,对该建筑的安全有影响。因此,各级领导很关心藏书楼的安全。隧道院承担“保护”任务后,制定了以防为主,本体加固保护为辅的方案:监理施工,多手段的监测——反馈的办法分析诸因素的影响,不断调正施工方案,达到精心施工。并建立了土体水平位移和地表沉降的关系;土体水平位移和支撑轴力的关系;地表沉降和建筑物、地下管线变形的关系。从而达到在施工条件较差的情况下,保住了藏书楼建筑的整体安全。
Xujiahui collection of books is known at home and abroad ancient buildings, located in the west of Xujiahui Metro Station, the initial projections, the construction of the subway station, the safety of the building. Therefore, leaders at all levels are very concerned about the safety of the library. After undertaking the task of “protection”, the Tunnel Academy has formulated a plan that is mainly based on prevention and supplemented by ontology reinforcement and protection: supervision and construction, monitoring by means of multiple means - feedback measures to analyze the impact of various factors, and constantly adjust the construction plan to achieve meticulous care construction. And the relationship between horizontal displacement of soil and surface subsidence is established. The relationship between horizontal displacement of soil and supporting axial force, and the relationship between surface settlement and deformation of buildings and underground pipelines are established. So as to achieve the construction conditions in the case of poor, to keep the overall safety of the library building.
