Scope

Main technical content: The seepage detection technology for foundation pit retaining structures, with non-destructive testing technology as the core, can conduct a "pre-examination" of the quality of the foundation pit retaining structures, detect potential "hidden dangers" in advance, and effectively reduce construction risks. In order to standardize and unify the technical requirements for relevant detection, ensure the quality of detection results, and give full play to the role of seepage detection technology in ensuring the safe construction of foundation pits, the methods of seepage detection for foundation pit retaining structures in Shanghai area (array current field method and resistivity tomography) are described in detail and comprehensively in terms of applicable conditions, equipment requirements, implementation process, selection of detection parameters, and data processing and interpretation. This can provide scientific and reasonable guidance for relevant detection and comprehensively ensure the safety of foundation pit construction.
