Abstract

The invention discloses a foundation pit upheaval-resistant stability analysis method based on arc sliding. The method comprises the following steps of creating a theoretical model for foundation pitupheaval-resistant stability calculation based on arc sliding; respectively solving the divided first area, second area and third area according to the sliding surface form and the stress condition ofthe soil body inside and outside the pit to obtain an optimization model and analytical solutions of anti-sliding moment and sliding moment at different areas; adopting a universal programming language VB to perform programmed calculation on an optimization model, and inputting foundation pit and soil layer related information; separating the soil layers according to the underground water level and permeability, and assigning the weights of the corresponding soil layers; re-adjusting the soil layer according to the last supporting position, the excavation depth position of the foundation pitand the bottom position of the enclosure structure, and assigning corresponding information; respectively calculating three anti-sliding moments, three sliding moments and three construction load sliding moments; and calculating the anti-upheaval safety coefficient of the foundation pit according to a formula.

Description

technical field [0001] The invention relates to the technical field of foundation pit support design, in particular to a foundation pit anti-uplift stability analysis method and a computer readable medium. Background technique [0002] The anti-uplift stability check of the foundation pit is a very critical design content in the design of foundation pit support. It is not only related to the stability and safety of the foundation pit, but also closely related to the deformation of the foundation pit. Many scholars at home and abroad have studied the calculation of foundation pit anti-uplift stability. For example, Mana et al. proposed a stability factor of safety method for estimating the maximum displacement of the retaining wall and the maximum settlement of the ground outside the pit. Liu Guobin et al. gave the calculation process of the circular sliding anti-heaving analysis mode, including the sliding moment and anti-sliding moment of each area. The calculation formul...
