Method for predicting water leakage amount of leakage point of waterproof curtain
The invention relates to the technical field of groundwater control in geotechnical engineering, and particularly discloses a method for predicting the water leakage amount of a waterproof curtain leakage point, which comprises the following operation steps: S1, selecting any one exploratory hole in a structure range to explore a generalized bottom layer, and obtaining related data such as the number of water-bearing layers with the structure affected; s2, the foundation pit is compared as a water collecting gallery, a water collecting gallery unit length side infiltration flow calculation model is established, the single-side unit length flow Q is calculated, and the calculation formula of the single-side unit length flow is as follows: S3, a water stop foundation pit side wall water leakage model is established; according to the calculation formula of the single-side flow per unit length in S2, the derivation formula is as follows: the daily water leakage per linear meter of the leakage point of the waterproof curtain is obtained. According to the calculation method for predicting the water leakage amount of the leakage point of the waterproof curtain, the amount of water permeating into the foundation pit from the leakage point can be calculated relatively accurately, the number and power of the drainage wells and the water pumps in the pit are verified, and whether pumping drainage of the water amount of the leakage point can be met or not on the basis of the original drainage water amount is judged.
