Embodiment Construction

[0017] This temperature stress analysis method for crack prevention of concrete dams adopts a three-layer B / S architecture design, in which:

[0018] The first layer, presentation layer: data collection layer, distributed in the form of web pages, system management interface, data management, graph display of results, early warning information, the presentation layer separates the system's operation interface from the system's function realization;

[0019] The second layer, application layer: including WEB server and application server and the realization of middleware technology. The business logic implementation layer of the application system is the core part of the system. It receives function requests from the presentation layer and is the logic to realize various business functions. Entities, these logical entities are implemented as database triggers and stored procedures, SapTis simulation calculation components, anti-analysis control components and result processing c...

Abstract

The invention discloses a temperature and stress analysis and back analysis method used for crack control of a concrete dam. The temperature and stress analysis and back analysis method includes that a design of a three-layered B / S structure is adopted, wherein a first layer is a presentation layer, namely a data acquisition layer, a second layer is an application layer comprising a WEB server and an application server as well as implementation of the middleware technology, a third layer is a data layer used for storing and managing various information by adopting an SQLserver database; the structure comprises a data acquisition and analysis module, a simulation calculation module, a back analysis module and a post-processing analysis warning module. Through the three-layered structure and the four modules, temperature and stress changes of concrete during construction can be tracked and analyzed in real time, so that the current temperature and stress can be timely known and future temperature and stress can be predicted.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and in particular relates to a temperature stress analysis and back analysis method for crack prevention of concrete dams. Background technique [0002] Water conservancy and hydropower projects are developing in a large-scale direction, with various construction methods and fast construction speed, but concrete cracks during construction are a common problem, so there is a saying that "no dam will not crack". There are many examples of serious cracks in the construction period or operation period both at home and abroad. Some projects have been delayed for several years and have been forced to postpone water storage and power generation; some dams have seriously affected safety and normal use due to cracks, and even scrapped. Most of the dam crack accidents are caused by temperature stress, especially the cracks during the construction period. [0003] So f...
