Abstract

The invention discloses a method for determining the diameter of a sprayed jetted pile based on a long-short memory neural network. Diameter; S3: Preprocess the collected construction parameters, pile diameter and corresponding stratum parameters and divide the training set and test set; S4: Input the divided training set into the bidirectional long short-term memory neural network for training , adjust the parameters of the two-way long-short memory neural network to obtain a trained two-way long-short memory neural network, and the trained two-way long-short memory neural network is used to calculate the pile diameter of the rotary jetting pile; S5: Set the preset rotary jetting pile construction parameters And the stratum parameters are input into the pile diameter determination method to determine the pile diameter of the rotary jetted pile. The invention utilizes the long-short memory neural network method with time series data processing capability to ensure the pile diameter design and construction quality of the rotary jetting pile.

Description

technical field [0001] The invention relates to the technical field of rotary jetting piles, in particular to a method for determining the diameter of rotary jetting piles based on a long-short memory neural network. Background technique [0002] The high-pressure jetting pile construction technology is widely used in building foundation reinforcement, foundation treatment, anti-seepage and water-stopping, and slope protection due to its simple process, high pile strength and low cost. The construction of high-pressure rotary jet pile is to use a drilling rig to drill the rotary jet grouting pipe and nozzle at the design elevation of the pile bottom. It is sprayed out at medium and high speed to form a liquid stream with high energy concentration, which directly destroys the soil. During the spraying process, the drill pipe is rotated and lifted, so that the slurry and the soil are fully stirred and mixed, and a columnar consolidated body with a certain diameter is formed in...
