钢纤维高强混凝土井壁极限承载力数值计算

Numerical Simulation on Ultimate Load of Steel Fiber Reinforced High Strength Concrete Shaft Lining

我国新建井筒所穿越的表土层越来越厚,急需提高井壁结构的强度,越来越多的井壁采用钢纤维高强混凝土。将影响该种井壁水平极限承载力的主要因素进行无量纲化,通过数值计算试验,发现了井壁水平极限承载力与影响因素之间的规律,归纳得到了计算公式。

With the surface soil through which the newly constructed shaft lining in our country goes deeper and deeper,more and more SFRC are used in the shaft lining in order to increase the intensity of the shaft lining structure.The author nondimensionalized the factors affecting the horizontal ultimate load of SFRC shaft lining.The rules between horizontal ultimate load and factors are discovered through numerical simulation,formulas are acquired through regression.
