水下工作的混凝土结构强度影响因素分析

经常在水环境中工作的混凝土建筑,在外界水压及混凝土内外渗透压力的影响下,水会渗透到混凝土结构中。孔隙水的存在,不仅会使混凝土内部产生孔隙水压力,而且外界水渗入时携带的某些微粒子对混凝土产生造成化学侵蚀,使混凝土的力学性能发生改变,对混凝土结构的强度和耐久性产生一定的影响。因此,本文主要对在水环境工作下混凝土结构强度的影响因素进行了分析,为混凝土结构设计提供依据。

Analysis of factors affecting the strength of the concrete structure underwater

Under the influence of external water pressure and internal osmotic pressure, water will penetrate into the concrete structure which located in water. The presence of pore water, not only makes the inside of concrete pore water pressure increased but caused chemical erosion by some particles carried by the outside water to seep into the concrete. It changed the mechanical properties of concrete, and has a certain impact on the strength and durability of concrete structures. Therefore, this paper mainly analyses the influencing factors of the structural strength of the concrete under the water environment, it provides the reference for the design of concrete structures.
