Application of Double Row Piles Anchor Cable Support System in Soft Soil Foundation Pit

In order to study the variation law and feasibility of internal forces of double row pile anchor cable structure in soft soil foundation pits, this paper studies the variation law of parameters such as horizontal displacement and bending moment of the structure through theoretical calculation and numerical simulation (taking a soft soil foundation pit project in Dongguan as an example), and compares the measured values with the calculated values.The unloading plate can provide a counter bending moment to increase structural stability.The theoretical and numerical calculation curves of the horizontal displacement of the support structure are basically similar to the measured curves, and the deformation values are within the allowable range of the specifications. This indicates that the double row pile anchor cable combined with the unloading plate system has a good effect on the support of foundation pits in soft soil areas where the site is limited.
