    本文对裂缝产生机理做了分析计算.认为产生裂缝是因为混凝土干缩受到基本不干缩的浆砌石阻碍后产生的拉应变超过混凝土极限拉应变所致,提出了防止产生裂缝的措施,并针对四里岩的现状提出了处理方案.

    A great deal of circular crackes were found at Siliyan Reservoir's covered way in 1998. It is considered that concrete's dry contraction was impeded by grouted stone , and producing dragging strain which led to crack's formation . The measures of preventing and controlling the cracks were proposed.
