The diaphragm wall plays an important role in the safe construction of foundation pits, and it is crucial to accurately monitor its deformation real time. Traditional monitoring methods often face challenges achieving distributed monitoring, cost using fiber optic sensors for real-time can be prohibitively high. To improve efficiency accuracy deep wall, this paper proposes a hybrid method that combines ultra-weak Bragg grating (UWFBG) technology traditional FBG sensors. This distributed-discrete optical approach allows continuous, high-resolution data collection along while providing targeted, measurements at critical locations. Fiber crack testing concrete beam structures was carried out verify evaluating health status data. An engineering case study developed validate feasibility method. results demonstrated effectively captures overall distribution enabling key areas, including detection initiation propagation. proposed offers significant advancement enhanced accuracy, spatial coverage, ability detect both macro-scale trends micro-scale anomalies, which particularly beneficial complex underground structures.

Rainfall and reservoir water level (RWL) fluctuations are the most important factors affecting landslide stability. Although extensive research has explored stability under combined effect of rainfall RWL fluctuation, quantitative investigations on individual contributions fluctuation to limited. To address this issue, taking Majiagou in Three Gorges Region (TGR) as an example, seepage field was simulated analyzed three different scenarios: rainfall; fluctuation; fluctuation. The corresponding condition scenarios evaluated. results show that is critical factor governs landslide. Specifically, when drops rapidly from 165 m 145 m, with average rate 0.859 m/d, safety decreases significantly. reason rapid decline creates outward-directed forces promote slope deformation. In contrast, a limited stability, only decreasing exceeds 50 mm/d. This because force directed outward develops reaches certain threshold, leading reduction slope’s factor. addition, study reveals generates synergistic amplification mechanism. variation hydrological conditions significantly arithmetic sum rainfall-induced RWL-induced variation. helps us understand how affect by altering field, which crucial for preventing landslides.
