Embodiment

[0027] like Figure 1-6 As shown, the embodiment of the present invention provides a seepage analysis method considering the defects of occlusal piles, including the following steps:

[0028] S1. Design and manufacture of defect-free pile model S-1

[0029] There are no defects in this model. As an initial model, the diameter of the occlusal pile model is the design diameter D, the occlusal amount is the design size a, and the length of the pile body is the design length H. The schematic diagram of the model is as follows figure 1 , figure 2 shown;

[0030] S2. Design and make diameter defect model S-2

[0031] As the depth increases, it becomes more difficult to control the accuracy of the pile diameter. The diameter of the occlusal pile becomes smaller as the excavation depth increases. The diameter of the pile top in this model is the design diameter D, and the diameter of the pile bottom is 0.9D. The increase of the depth decreases linearly, then the pile diameter at ...

Abstract

The invention provides a seepage analysis method considering secant pile defects, and relates to the technical field of underground construction engineering. The seepage analysis method considering the secant pile defects comprises the steps that S1, a defect-free pile body model S-1 is designed and manufactured; S2, a diameter defect model S-2 is designed and manufactured; S3, a perpendicularitydefect model S-3 is designed and manufactured; S4, a comprehensive defect model S-4 is designed and manufactured; and S5, during secant pile seepage condition analysis, the four models manufactured inthe step S1 to S4 are substituted in sequence for analysis and calculation, and data are obtained, so that the influence on a vertical shaft and a surrounding environment is known when the various defects exist in a secant pile. According to the seepage analysis method considering the secant pile defects, the four models are established, the influence of the various defects of the secant pile onthe vertical shaft and the surrounding environment is known through analysis and calculation; and the provided seepage analysis method considering the secant pile defects solves the problem that the defects of the secant pile cannot be considered during seepage analysis, so that a calculation result better conforms to engineering practice.

Description

technical field [0001] The invention relates to the technical field of underground construction engineering, in particular to a seepage analysis method considering the defects of occlusal piles. Background technique [0002] Occlusion piles are often used as enclosure and water-stop structure for shaft excavation. When the occlusal piles have geometric defects or the occlusion is not tight due to insufficient vertical precision of the occlusal piles, the groundwater around the shaft will flow into the shaft, which will affect the construction of the shaft in the lightest cases, and cause damage to the shaft wall structure in severe cases. At present, there is a lack of corresponding analysis models and methods for occlusal pile defects, and it is impossible to judge the impact of occlusal pile defects. Therefore, it is necessary to invent a seepage analysis method that considers occlusal pile defects to evaluate the impact of occlusal pile defects on shafts and surrounding e...
