Joints such as transverse and longitudinal joints, and cracks caused by all kinds of factors are quite common in concrete dams.
混凝土坝工程横缝、纵缝，以及由于各种因素引起的混凝土裂缝是普遍存在的。
The results demonstrate that the thermal stress could meet the design criteria even without longitudinal joints so long as placement temperature is controlled reasonably.
计算分析表明，只要合理控制浇筑温度，即使不设纵缝，坝体温度应力也能满足设计要求。
