摘要
随着科学技术和国民经济的迅速发展.根据材料和结构的真实状态(缺陷的存在和演化)进行合理设计和分析计算势在必行。由于材料损伤具有非线性分布等特点和量测技术仍然落后于需要,使固体力学场中的真实状态不容易获得。现从宏观唯象学理论出发,对黄壁庄水库副坝防渗墙的墙体材料一混凝土样本进行的损伤力学研究,获得了防渗墙墙体混凝土的损伤变量。这是第四纪地质条件下经冲击钻造孔并进行水下浇筑混凝土防渗墙工程资料的反馈。实践表明,黄壁庄水库副坝防渗墙混凝土的真实质量符合设计要求。分析结果,可供同类工程设计与施工参考。
The author tries to begin with macroscopical phenomenology, to make a damage mechanics study for the materials of the seepage cutting wall (the concrete sample) of the Secondary Dams in Huangbizhuang Reservoir, and at last the damage variables of the seepage cutting wall are obtained. This is the feedback of the seepage cutting concrete wall construction materials after masonry drills boring and casting underwater in the conditions of Quaternary geology. It has been proved by practice, that the real quality of the seepage cutting wall concrete of The Seconda-ry Dams in The Reservoir is qualified to the design demand, and its results can be used by other projects for reference.
