Method for predicting ground surface settlement caused by shield construction based on neural fuzzy inference system

Abstract

The invention discloses a method for predicting ground surface settlement caused by shield construction based on a neural fuzzy inference system. The method comprises the steps of selecting main influence factors of ground surface settlement caused by shield construction, forming an effective data set by the main influence factors, calculating the effective data set by means of a ground surface settlement prediction model built by the neural fuzzy inference system, and therefore obtaining a prediction result and performing model verification according to the prediction result. Accordingly, the method for predicting ground surface settlement has the advantage of being high in prediction precision, and is easy to use, small in calculated quantity, high in generalization, thereby having high practicability, and the novel technical scheme can be provided for predicting ground surface settlement caused by shield construction.

Description

technical field [0001] The invention relates to a method for predicting land surface subsidence, in particular to a method for predicting land surface subsidence caused by shield construction based on a neural fuzzy reasoning system. Background technique [0002] In the current actual construction, due to the lack of practical and accurate prediction methods for surface settlement caused by shield tunneling, at present, it is mainly based on the experience of the shield driver combined with the feedback of the monitoring value of the surface settlement to control the progress of shield tunneling. The monitoring value has exceeded or is close to the limit, and the shield driver will adjust the speed of shield construction. This method has the following disadvantages: the first disadvantage is that the control of shield tunneling depends to a large extent on the shield driver's operating skills, and the experience of shield tunneling in similar formations and buried depths; th...

Problems solved by technology

This method has the following disadvantages: the first disadvantage is that the control of shield tunneling depends to a large extent on the shield driver's operating skills, and the experience of shield tunneling in similar formations and buried depths; the second disadvantage is surface settlement The information feedback is too late. When the shield driver gets the surface settlement information, excessive settlement or uplift has already occurred. In cities with dense pipelines and buildings, the feedback process is slow, which may cause excessive losses
