水利工程低弹模混凝土防渗墙适应性评价研究

Adaptability Evaluation of Low Elastic Modulus Hydraulic Concrete Cutoff Wall

低弹模混凝土防渗墙由于其弹模小,与周围变形能够较好协调,在许多水利工程中得到应用,但由于工作条件较为复杂,其适应性影响因素较多,目前尚没有一个完全成熟的评价体系及方法。因此,针对水利工程特点,建立低弹模混凝土防渗墙适应性评价体系,并借助多层次模糊综合评判模型,结合工程实例加以分析。分析结果符合工程实际,表明该适应性评价体系有效,评价方法可行,为今后水利部门对低弹模混凝土防渗墙在实际工程的适应性评价提供了一种手段。

Owing to its small elastic modulus and the better surrounding deformation co-ordination,the low elastic modulus cutoff wall has been applied in a number of water conservancy projects.With the more complex working conditions and more adaptive evaluation factors,there is currently no a full-mature evaluation method.Thus,from the hydraulic characteristics an adaptability evaluation system of low elastic modulus concrete cutoff wall was established,and,an example was analyzed using multi-level fuzzy comprehensive evaluation model.The results indicated that this is an adaptive and effective evaluation system,its analytic results coincide with engineering practice.the method provides a means of adaptation evaluation for the future water sector.
