水压力环境下混凝土断裂研究综述

摘要

随着工程建设中水力劈裂作用受到越来越多的重视，迫切的需要水工混凝土的水力劈裂准则作为工程建设依据。本文对现有混凝土断裂研究、水对混凝土性能影响以及国内外混凝土水力劈裂试验与模拟研究等进行了综述，结合水对混凝土性能的影响，提出了多场耦合作用下的断裂分析等需进一步研究的问题。%We urgently need to hydraulic fracturing hydraulic concrete guidelines as a basis for the construction, as the hydraulic fracturing is more and more emphasis on the construction. This paper studies the current fracture of concrete, the effect of water on properties of concrete and concrete testing and simulation of hydraulic fracturing. Describes the status of the concrete structure of hydraulic fracturing. Combined effect of water on concrete performance, several prospects are proposed, such as fracture analysis of multi-ifeld coupling.
