Method for constructing tunnel and adjacent historical buildings

Abstract

The invention belongs to the field of underground engineering construction, and discloses a method for constructing a tunnel and adjacent historical buildings. The processing method comprises the steps of: (a) quantizing closeness levels of the tunnel and existing historical buildings; (b) evaluating current safety levels of the existing historical buildings; (c) analyzing a safety risk level of constructing the tunnel close to the historical buildings, and according to the safety risk level, determining a specific response solution of neighbor historical building protection and control; and (d) tracking and observing influence of tunnel construction on foundation settlement of the historical buildings in real time, and carrying out real-time feedback and active control on safety states of the historical buildings. By the method disclosed by the invention, when tunneling construction safety is ensured, engineering cost is saved, and a positive guidance decision is provided for an engineer for safety management on historical buildings around tunnel construction; and the method is particularly suitable for integral protection and control on historical building groups close to tunnel construction.

Description

technical field [0001] The invention belongs to the field of underground engineering construction, and more specifically relates to a construction method for a tunnel adjacent to a historical building. Background technique [0002] To some extent, historical buildings reflect the degree of evolution of urban expansion and the development of local history and culture. Historical buildings belong to cultural heritage, and how to effectively protect and manage them is an engineering issue that has attracted much attention. These historical buildings generally have certain aging phenomena, and it is difficult to reach the designed bearing capacity. During long-term use, some structural components may be damaged. In recent decades, in order to solve urban complex diseases such as population growth, space constraints and environmental problems, urban tunnel projects have been carried out on a large scale. Tunnel excavation will inevitably lead to ground disturbance, which will in...

Problems solved by technology

[0004] Aiming at the above deficiencies or improvement needs of the prior art, the present invention provides a construction method for tunnels adjacent to historical buildings. By adopting technologies such as risk assessment, numerical simulation, and value engineering as a whole, it is proposed that when the tunnel construction environment is adjacent to historical buildings, construction method, thus solving the technical problems of time-consuming and high-cost numerical simulation in predicting the damage of buildings adjacent to tunnel excavation
