摘要
塑性混凝土是近年来发展的一种新型防渗墙体材料,在防渗工程中得到了广泛的应用,墙体结构的可靠性对防渗效果起到至关重要的作用。本文采用有限元计算方法,研究了塑性混凝土防渗墙在静力荷载以及地震荷载作用下的变形特性和应力特性,并且对其可靠性作出评价。结果表明,塑性混凝土防渗墙和墙体外围土体之间变形协调,应力状态良好,具有较好的抗震性能。
Plastic concrete is a new material used in cutoff wall in recent years,and has been widely used in impervious works.The reliability of the wall structure plays a vital role in the effect of impervious.In this paper,the characteristics of deformation and stress of plastic concrete cutoff wall under static and dynamic load were studied and its reliability was evaluated by the method of finite element.The results indicated that plastic concrete cutoff wall can deform coordinately with the surrounding soil,with a good stress condition and a good seismic performance.
