Embodiment

[0023] Such as figure 1 As shown, a method for identifying and processing the settlement mode of shield tunnel construction, the method includes the following steps: 1) collecting the surface settlement monitoring data of the shield tunnel, and storing it in the database; 3) analyze and obtain the construction parameters associated with the mode to provide guidance and basis for construction optimization.

[0024] Such as figure 2 As shown, the analysis and identification process of the lateral settlement curve mode includes the following steps:

[0025] Step 301) Carry out risk value judgment and settlement / uplift judgment, if it is judged as subsidence type, then proceed to step 302);

[0026] Step 302) judging whether the curve is an antisymmetric type, if judging otherwise proceed to step 303);

[0027] Step 303) to judge the symmetry of the curve, if it is judged to be yes, then go to step 304), otherwise go to step 306);

[0028] Step 304) carries out curve normalit...

Abstract

The invention relates to a method for identifying a settlement pattern during shield tunnel construction. The method comprises the following steps of: 1, acquiring ground settlement monitoring data of a shield tunnel and storing the data into a database; 2, analyzing and identifying a transverse settlement curve pattern and a longitudinal settlement curve pattern of the tunnel and determining the pattern of the tunnel; and 3, analyzing to obtain construction parameters associated with the pattern of the tunnel, so that guidance and basis are provided for construction optimization. Compared with the prior art, the method has the advantages that the current situation that monitoring data and construction parameters can only be identified manually is changed; and automatic identification of the curve pattern, automatic generation of a curve analysis result and fitting of relevancy of various parameters are realized, so that the guidance and basis are provided for construction optimization.

Description

technical field [0001] The invention relates to the field of shield tunnel construction, in particular to a method for identifying and processing a shield tunnel construction settlement mode. Background technique [0002] With the continuous development of my country's economy, the demand for underground rail transit and municipal engineering pipelines in large and medium-sized cities is increasing year by year. In recent years, a large number of underground railways and large-diameter municipal pipeline projects have been built in economically developed cities. In coastal soft soil areas, the shield tunneling method is often the first choice for underground tunnel construction due to its high degree of mechanized construction, mature construction technology, and high level of environmental protection requirements. [0003] In shield tunneling engineering, surface settlement data is considered to be one of the important indicators reflecting the impact of construction on th...
