Different structural measures for thermal crack control have different effects . quantitative research has been done to see the effects of thermal crack control by slope roof in cshbb . control measures for design and construction were also presented 比较了各种裂缝控制措施的控制效果，从定量的角度考虑了坡屋面的抗裂效果，提出了控制小砌块建筑裂缝所应采取的设计和施工措施。
Using the developed computer program the wind flow around a cubic building model , a rectangle - section tall building and a gable - roof building are first numerical predicted , respectively . in the prediction the single - area and multi - area grid refinement approaches are respectively used and the numerical results are compared with the wind - tunnel test results and the numerical results without grid refinement obtained by other researchers . this indicates that the proposed nonstaggered grid and refinement scheme is not only valid and easy to be car 采用编制的计算程序首先对一立方体建筑模型、一矩形截面高层建筑和一双坡屋面建筑的绕流风场进行了模拟计算，分别采用单域和多域加密方案对建筑周围的网格实施了局部加密，数值模拟结果与风洞试验结果以及其他研究者的非加密计算结果进行了比较。
