Abstract

The invention discloses an advanced forecasting method of soil shield tunnel construction disasters. An advanced detecting device is arranged in front of a shield tunneling machine; lateral resistance, end resistance and porewater pressure of a soil layer can be detected by using an advanced probe to determine the property of the soil layer, then the soil layer property determining result is conveyed in a shield tunnel construction control center, a soil layer distribution and property three-dimensional model is formed, and a soil layer distribution and property prediction three-dimensional model corrected continuously within a larger range is automatically generated, so that the front soil body engineering property is judged, the construction scheme is corrected in time, safety measures are taken, the construction cost is reduced, the construction quality is ensured, and major safety accidents are avoided. Through the advanced forecasting method, the construction environment can be predicted, the construction scheme is optimized, safety measures are taken, the advanced forecasting method is safe and convenient, can be suitable for different properties of soil layers, and is economic and accurate in shield tunneling construction, and the material is saved.

Description

technical field

[0001] The invention belongs to the technical field of civil engineering construction, and in particular relates to a method for advanced forecasting of soil shield tunnel construction diseases. Background technique

[0002] The shield is a fully enclosed tunnel boring machine (a construction tool that can support the pressure of the stratum and excavate in the stratum). The lining segments provide counterforce and can excavate continuously. While keeping the excavation surface and the surrounding soil stable, tunnel excavation and excavation were carried out, segments were assembled in the shield tail to form a lining, grouting was performed in time, and the tunnel was built without disturbing the soil as much as possible. There are three main points in the shield construction method: the stability of the excavation surface, the high-precision advancement of the shield along the design route (shield posture, tunnel direction), and lining operations.
