Alpine region dam deformation control method, device and controller

Abstract

The invention discloses an alpine region dam deformation control method, device and controller, wherein, the dam body comprises a concrete face plate and a rockfill dam; the dam body deformation control method comprises the following steps: obtaining Duncan-Zhang E-B model parameters of dam body materials and rheological model parameters of the rockfill dam;; evaluating the safety of the dam bodyaccording to the parameters of the Duncan-Zhang E-B model and the parameters of the rheological model; at least one of a dam material zoning, a filling procedure, and a concrete slab placement timingis determined based on the evaluation results. By means of engineering properties of dam materials such as Duncan-Chang E-B model parameters, and the rheological properties of rockfill, the safety ofconcrete face rockfill dam is evaluated by numerical analysis, the reasonable selection of dam material zoning and the scientific basis for filling procedure and placement timing of concrete face slabcan solve the problems of concrete face slab dislodging and cracking caused by excessive deformation of rockfill dam, which provides a guarantee for the safe operation of concrete face slab rockfilldam.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and in particular relates to a deformation control method, device and controller of a dam body in an alpine region. Background technique [0002] The deformation of the concrete face rockfill dam is affected by many factors, such as the compactness of the dam body filler, the shape of the river valley, the geological conditions of the dam foundation, and the filling method and procedure. The consequences of excessive deformation of concrete face rockfill dams are: excessive deformation of the face plate and peripheral joints leads to damage to the anti-seepage system and serious leakage, which endangers the normal operation and safety of the dam. The actual monitoring results of many built rockfill dams at home and abroad show that the rockfill body has rheological properties. The rheological deformation of the face rockfill dam deteriorates the mechanical pr...
