Abstract


City Tunnel excavation inevitably be surrounding soil disturbance , and thus have an impact on neighboring buildings , severe to endanger the safety of the building . With the improvement of the level of economic development and urbanization , increasingly dense surface buildings , increasing the value of buildings , tunnel excavation and surface buildings have become increasingly prominent . Therefore , the study of surface movement and deformation caused by urban tunneling on adjacent buildings , the extent of the damage of the evaluation of the building , appropriate defensive measures for the damage the building has an important significance for ensuring the safe and proper use of the building . Qingdao end wiring Qinghuang Cross Harbour Tunnel , for example , in-depth study of the following aspects ZK1 180 ~ ZK1 240 ff right side of the # 1 building for tunnel Yunnan Road mainline . ( 1 ) using the software of surface movement and deformation caused by tunnel excavation subsidence is expected based on the probability integration method is calculated , and a detailed analysis of the characteristics of the change ; ( 2) using the finite element software ANSYS , surface movement and deformation as the initial the condition input surface buildings , according to the stress and strain results further evaluation of tunnel excavation damage to the building on the ground ; (3) from the tunnel construction , ground reinforcement , built the structure of the building resistance to deformation , the proposed buildings ontology reinforcement , five aspects of building design methods and analysis of tunnel excavation surface near the building damage caused by defensive measures to ensure that the tunnel excavation with minimal damage to the buildings on the ground , in order to achieve the tunnel excavation and protection of ground-level structures coordination ; (4) ArcGIS geographic information system -based platform , the strong secondary development function in VB , integrated professional tunnel excavated surface buildings damage evaluation and defense space policy-making system , the preparation of a professional data management module , buildings , the damage evaluation module and defense decision-making module . The system was developed rich geographic information system , the the program modular building damage and tunnel excavation area defense decisions visualization .
