Monitoring method, device and related equipment of soil mass consolidation settlement

Abstract

The invention discloses a monitoring method of soil mass consolidation settlement. The monitoring method comprises the steps that satellite image data and field measurement data are obtained; a PS observation network is constructed according to the satellite image data; the field measurement data is processed by a least square fitting method, and a non-linear settlement and deformation model is constructed; a DS observation network is constructed by the non-linear settlement and deformation model based on the PS observation network; the PS observation network and the DS observation network aregeocoded and projected vertically to obtained a vertical deformation map; and soil mass consolidation settlement data is analyzed according to the vertical deformation map, and soil mass consolidation settlement monitoring is achieved. The monitoring method effectively solves the mismatch problem between linear phase deformation model and non-linear consolidation settlement of early filling, andimproves the success rate of soil layer consolidation settlement monitoring. The invention further discloses a monitoring device, equipment and a computer readable storage medium for soil mass consolidation settlement, and the monitoring device, equipment and the computer readable storage medium all have the beneficial effects.

Description

technical field [0001] The present application relates to the field of civil engineering, in particular to a monitoring method for soil consolidation and settlement, and also relates to a monitoring device, equipment and computer-readable storage medium for soil consolidation and settlement. Background technique [0002] Land reclamation (filling) land is the most direct and effective way to solve the shortage of urban land, especially for coastal port cities with land shortage. Compared with Western countries in Europe and the United States, China's reclamation process is relatively short. Hong Kong, as a representative of China's urban land reclamation, has a long history of reclamation, a large number, a large scale, and a wide range of uses. Its reclaimed land is mostly used for construction land such as airports, ports, entertainment facilities, large shopping malls, etc. Therefore, early settlement monitoring of reclaimed land is particularly important for the subseq...

Problems solved by technology

[0004] However, for the ground deformation monitoring of newly reclaimed land, the traditional MTInSAR processing method still has technical defects and deficiencies

The most prominent one is that the rapid settlement in the early stage of soil consolidation is likely to lead to serious phase decoherence, which directly affects MTInSAR, especially the high-resolution PSI (Persistent Scatterer Interferometry, permanent scatterer synthetic aperture radar interferometry) technology in the detection of filling The reason for the success rate of the early settlement of soil is that in the traditional technical field, the linear phase model is generally used to monitor the ground deformation during the early consolidation and settlement of the fill, but the actual deformation process of the ground is nonlinear, so it will be As a result, there is an obvious mismatch between the actual ground deformation and the linear phase model, which seriously affects the success rate of early fill consolidation settlement monitoring
