混凝土早期弹模反应动力学模型及其应用
Dynamic model for concrete early-age response of elastic modulus and its application
摘要
Abstract
The general law of concrete early-age hardening is expatiated, and based on this, a kinetic model for the early-age development response of elastic modulus is put forward herein, and then, this model is applied to the simulation analysis of a square culvert structure within the South-to-North Water Transfer Project. The engineering actual case shows that the fact of the early-age development of the concrete elastic modulus during the high temperature of summer is faster than that during the low temperature of winter can be well-simulated by this model, therefore, the causation of the development of the cracking in the central part of the culvert is better explained and both the applicability and reliability of the model are demonstrated as well.关键词
