Research on Crack Prevention Method for Long Concrete Foundation Slab of Pumping Station

Article Preview

Abstract:

The foundation slab is the key structure of a pumping station. For such a hydraulic structure cracking is not permitted because it will cause heavily seepage and other disaster. Temperature control is an important way to prevent cracking. With the aid of finite element method for temperature field and stress field simulation, research is carried out for a 43.5m long mass concrete foundation slab of a pumping station poured in different seasons. Different measures, such as pipe cooling, surface preservation and pouring temperature control, are tried to control the temperature and stress. This research gets some useful results, and the measures proposed have a significant reference to similar projects.
