断裂力学对水工结构的某些问题确是一个有力的手段。对水工结构物,断裂力学可能有二种用途,即分析已建成的结构物中某些严重裂缝的稳定性,和用断裂力学的概念改进某些水工结构物的设计方法。原文中主要分析了浇筑块中贯穿裂缝的稳定性和配筋的作用问题,并提出了用断裂力学改进重力坝稳定计算方法的设想。这些问题都是有现实意义的。现提以下几点看法供参考。 Fracture mechanics of the hydraulic structure of some of the problems is indeed a powerful tool. For hydraulic structures, fracture mechanics may serve two purposes: analyzing the stability of some of the severely fractured structures already built and improving the design of some structures using the concept of fracture mechanics. In this paper, the stability of the pouring block and the effect of reinforcement are mainly analyzed, and the idea of ​​using fracture mechanics to improve the stability calculation of gravity dam is proposed. These questions are of practical significance. Here are some points for reference.
