Background

The basement pressure-bearing water surge refers to a water surge phenomenon occurring in a basement or a subterranean space due to excessive water pressure. Specifically, basement confined water surges can cause serious damage to buildings, including leakage and structural damage, and steel casing cofferdams are a common method of plugging to prevent basement confined water surges. The steel sleeve body is a pipeline with high strength and corrosion resistance, before plugging, holes are needed to be drilled on a basement wall or floor, the steel sleeve is inserted into the holes, and the steel sleeve is sealed with surrounding structures by using sealing materials, so that a sealed cofferdam is formed, water gushes are prevented from entering the basement, and a building is protected from water pressure and water attack.

In the actual plugging process, a system for simulating the plugging is lacking, the position, the pressure and the intensity of the water surge cannot be predicted, corresponding plugging measures are difficult to take, meanwhile, as various water surge conditions cannot be simulated, a plugging method can be decided only by constructors at sites, the choice and the adjustability are poor, the risk in the whole plugging process is high, and due to the fact that a simulation system is lacking, constructors need to detect on site and test errors with a preset scheme, the most effective plugging scheme is difficult to obtain efficiently, and the whole construction efficiency is poor.

In cofferdam plugging simulation, a finite difference method converts a continuous physical model into a discrete numerical model, and a simulation result is obtained by approximately solving a difference equation.

The following discretized partial differential equations and their meanings are enumerated by the common differential format:

first, center differential format:

one-dimensional case: partial derivative: frac { \partial u } { \partial x } \ approx \frac { u_ { i+1} -u_ { i-1} {2\Delta x } $ }

Second partial derivative: frac { \partial x ≡2} \ approx } frac { u_ { i+1} -2u_i+u_ { i-1} { (\Delta x) ≡2} $

Two-dimensional case: lateral partial derivative: frac { \partial u } { \partial x } \ approx \frac { u_ { i+1, j } -u_ { i-1, j } {2\Delta x } $ }

Longitudinal partial derivative: frac { \partial u } { \partial y } \ approx \frac { u_ { i, j+1} -u_ { i, j-1} {2\Delta y } $ }

Second order lateral partial derivative: frac { \partial x ≡2} { \ approx ++u_ { i+1, j } -2u_ { i, j } +u_ { i-1, j } { (\Delta x) ≡2} $

Second order longitudinal partial derivative: frac { fraction 2u } { \fraction y 2} \ approx \frac { u_ { i, j+1} -2u_ { i, j } +u_ { i, j-1} { (\Delta y)/(2 } $)

Second, forward differential format:

One-dimensional case: partial derivative: frac { \partial u } { \partial x } \ approx \frac { u_ { i+1} -u_i } { \Delta x } $

Second partial derivative: frac { \partial x ≡2} \ approx } frac { u_ { i+1} -2u_i+u_ { i-1} { (\Delta x) ≡2} $

Two-dimensional case: lateral partial derivative: frac { \partial u } { \partial x } \ approx \frac { u_ { i+1, j } -u_ { i, j } { \Delta x } $ }

Longitudinal partial derivative: frac { \partial u } { \partial y } \ approx \frac { u_ { i, j+1} -u_ { i, j } { \Delta y } $

Second order lateral partial derivative: frac { \partial x ≡2} { \ approx ++u_ { i+1, j } -2u_ { i, j } +u_ { i-1, j } { (\Delta x) ≡2} $

Second order longitudinal partial derivative: frac { fraction 2u } { \fraction y 2} \ approx \frac { u_ { i, j+1} -2u_ { i, j } +u_ { i, j-1} { (\Delta y)/(2 } $)

Thirdly, backward differential format:

One-dimensional case: partial derivative: frac { \partial u } { \partial x } \ approx \frac { u_i-1 } { \Delta x } $

Second partial derivative: frac { \partial x ≡2} \ approx } frac { u_ { i+1} -2u_i+u_ { i-1} { (\Delta x) ≡2} $

Two-dimensional case: lateral partial derivative: frac { \partial u } { \partial x } \ approx \frac { u_ { i, j } -u_ { i-1, j } } { \Delta x } $

Longitudinal partial derivative: frac { \partial u } { \partial y } \ approx \frac { u_ { i, j } -u_ { i, j-1} { \Delta y } $

Second order lateral partial derivative: frac { \partial x ≡2} { \ approx ++u_ { i+1, j } -2u_ { i, j } +u_ { i-1, j } { (\Delta x) ≡2} $

Second order longitudinal partial derivative: frac { fraction 2u } { \fraction y 2} \ approx \frac { u_ { i, j+1} -2u_ { i, j } +u_ { i, j-1} { (\Delta y)/(2 } $)

In the above, u_i represents the function value at grid point $ (i, j) $, and $\delta x$ and $\delta $ respectively represent the lateral and longitudinal pitches of the grid, and the differential format approximates the values of the partial derivative and the second partial derivative by using the difference of the function values at adjacent grid points, so that the continuous differential operation is converted into a discrete differential operation, and by selecting the differential format and the grid resolution, a numerical solution satisfying the required accuracy can be obtained.

minimize:(1/(2*N))*||y-Xw||^2+alpha*||w||_1

Where y is the target variable, X is the feature matrix, w is the regression coefficient, N is the number of samples, and alpha is the regularization parameter.

The main characteristic of LASSO regression is that the regression coefficient of part of the features can be changed to zero by adding an L1 regularization term to the objective function, so that the selection of the features is realized. The characteristics enable LASSO regression to perform well in a high-dimensional data set, and the most relevant characteristics can be automatically selected, so that the characteristics with smaller contribution to the model are eliminated, and the complexity of the model and the risk of overfitting are reduced.
