Abstract

The invention discloses a method and a device for analyzing the influence of a variable temperature load on a roller compacted concrete gravity dam. According to the scheme, by analyzing different conditions of the roller compacted concrete gravity dam, the influence conditions of different change temperature loads on the roller compacted concrete gravity dam to be analyzed can be obtained. According to the scheme, a three-dimensional calculation model of the roller compacted concrete gravity dam to be analyzed is created. Boundary limiting conditions of the three-dimensional calculation modelare configured, meteorological data of the place where the roller compacted concrete gravity dam to be analyzed is analyzed and then analysis schemes under different conditions are designed. The configured three-dimensional calculation model is calculated under each analysis scheme to obtain the spatial distribution rule of the temperature and the stress of the three-dimensional calculation modelunder each analysis scheme. Finally, the calculation result of the three-dimensional calculation model is analyzed under the analysis scheme to obtain the influence of different change temperature loads on the roller compacted concrete gravity dam to be analyzed.

Description

technical field [0001] The present application relates to the technical field of construction engineering, in particular to an analysis method and device for the influence of changing temperature loads on roller compacted concrete gravity dams. Background technique [0002] The structural safety of the dam is a factor that must be considered when building a dam. The material for building a dam is generally concrete. Due to the influence of environmental factors, the concrete often produces some cracks. [0003] Among them, the temperature load is a main factor of mass concrete cracks. In the prior art, the temperature load caused by cement hydration heat (generally referred to as long-term temperature load) is mainly considered in the calculation of concrete temperature control and crack prevention, and this is used as the standard for formulating temperature control and crack prevention. . Specifically, the effects of long-term loads such as cement hydration heat and shor...
