Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0058] like figure 1 As shown, a dam horizontal displacement prediction method includes the following steps:

[0059] Step 1. According to the cause analysis theory of the dam horizontal deformation foundation, select the influencing factors.

[0060] The influence factors selected here are determined according to different actual situations. Here we choose the influence factors including water level H, temperature T, time effect t, and square H of water level under multiple periods of time. 2 , the cubic H of the water level 3 , the water level to the fourth power H 4 and the logarithm ln of aging t .

[0061] Step 2: Obtain the corresponding historical horizontal displacement data of the...

Abstract

The invention discloses a dam horizontal displacement prediction method. According to the method, firstly, high-dimensional factors are subjected to dimension reduction and correlation elimination based on typical cause analysis, and linear transformation vectors for overall prediction of two kinds of horizontal displacement, namely from the upstream to the downstream of a dam and from the left bank to the right bank of the dam, are obtained; secondly, samples are classified according to condition similarity based on cluster analysis, singular points are screened out, and classified regression and prediction are conducted on the basis of classification. In this way, noise interference and information loss caused by unbalance of sample quality and sampling can be avoided, sample information can be excavated more reasonably and sufficiently, a prediction result with a higher confidence level can be obtained, and a more practical decision-making assisting function is achieved.

Description

technical field [0001] The invention relates to a prediction method, in particular to a method for predicting the horizontal displacement of a dam. Background technique [0002] At present, my country's dam safety monitoring is generally in a special stage. Many old dams are about to reach the design reference period, and a large number of new dams are being put into operation. Therefore, it is necessary to predict the dam safety monitoring indicators to provide safety monitoring decision-making assistance. The main purpose of dam safety monitoring and analysis and evaluation is to grasp the current operating status of the dam and judge whether the dam is safe. At present, the working mode of dam safety monitoring and analysis is mainly to analyze historical observation data in combination with daily inspection methods, establish a mathematical monitoring model, analyze, evaluate and monitor the working performance of the dam, and analyze the important observation indicators....
