An early warning method for long-term ground settlement in a metro operation period in an urban high-density area

A ground subsidence and ground technology, applied in the direction of data processing applications, material inspection products, instruments, etc., can solve the problem that it is difficult to accurately determine the influence range of ground deformation in the subway operation area, lack of long-term ground subsidence classification and early warning indicators, and can not reflect the long-term ground Three-dimensional distribution of settlement and other issues

Problems solved by technology

The existing ground subsidence early warning system during the operation period of the subway has limitations. For example, the characterization of the subsidence only considers the cumulative subsidence, subsidence rate, etc., and cannot reflect the three-dimensional distribution of the long-term ground subsidence. The

Abstract

The invention provides an early warning method for long-term settlement of the ground in a metro operation period in an urban high-density area. The invention aims to provide an early warning method for long-term settlement of the ground in a metro operation period in an urban high-density area. The method has the characteristics of quantification, operability, practicability and representativeness, can comprehensively reflect and monitor the quality degree of long-term settlement of the ground in the subway operation period from different angles, and realizes reflection of the long-term settlement of the ground in the subway operation period by using early warning indexes as few as possible.

Description

technical field [0001] The invention relates to a long-term ground subsidence early warning method, which is suitable for long-term ground subsidence early warning caused by subway operation in urban high-density areas, and belongs to the field of urban tunnel engineering and urban geological disaster prevention and control. Background technique [0002] The urban subway is the main line of urban public transportation, with a large passenger flow, and is the lifeline project of the city. Its safe operation is directly related to the personal safety and property safety of passengers. As of the end of 2017, a total of 31 cities in mainland China have opened subways, with a total operating line length of 4,407km. In terms of the distribution of cities operating subways, nearly 90% of the operating mileage is concentrated in the Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta urban agglomerations urban dense areas. The research on the long-term settlement of Sh...
