Abstract

The invention provides a method for calculating the relative displacement of shield machine soil based on guiding data. The method includes: determining the geometric dimensions of the shield machine and components and the position of the reference point; collecting the parameters of the shield guiding system in real time; establishing the calculation of the relative displacement of the machine and soil according to the geometric dimensions of the shield machine and components, the position of the reference point and the parameters of the shield guiding system Model; according to the calculation model of the relative displacement of the machine and soil, the calculation formula of the relative displacement of the machine and soil at the node is obtained, and the relative displacement of the machine and soil at each node associated with the shield is calculated, and then the relative displacement of the overall machine and soil of the shield machine is obtained. The method for calculating the relative displacement of the shield machine soil based on the guidance system data of the present invention can track the space position of the shield machine in real time through the guidance data, and can understand the deformation influence of the shield machine on the surrounding soil in real time, so as to ensure the safe and efficient excavation of the shield machine .

Description

technical field [0001] The invention relates to the technical field of shield tunnel construction, in particular to a method for calculating relative displacement of shield machine soil based on guiding data. Background technique [0002] With the further advancement of China's urbanization, the construction of urban rail transit is also in full swing. Due to its small impact on the environment and other characteristics, shield construction has become the main method in the construction of urban rail transit. However, since new lines often have to pass through existing tunnels, pipe networks, surrounding buildings, roads, etc., a little carelessness will cause excessive deformation of surrounding buildings and structures, and even house collapse, pipeline rupture, surface subsidence, etc. Major accidents, causing serious loss of life and property. Especially in the soft soil substratum, it is very difficult to control the attitude of the shield, and it is easy to have a la...
