一、裂缝在不同条件下产生的规律,概括如下: 大开间比小开间出现裂缝的几率高且重;窗洞口大比窗洞口小出现裂缝的几率高且重;有暖气槽比无暖气槽出现裂缝的几率高且重;层数多比层数少出现裂缝的几率高且重;纵墙承重体系比横墙承重体系出裂缝的几率高且重;砌体强度低比砌体强度高出现裂缝的几率高且重;地基承载力低比地基承载力高出现裂缝的几率高
First, the cracks produced under different conditions, the law is summarized as follows: Large open than the small opening between the chance of cracks are high and heavy; window hole is larger than the window hole small cracks the probability is high and heavy; there is a warmer than the non-heating tank appears The probability of cracks is high and heavy; the number of layers is less than the number of layers; the probability of cracks is high and heavy; the ratio of the vertical wall bearing system is higher and heavier than that of the transverse wall bearing system; the strength of the masonry is lower than that of the masonry strength. The probability is high and heavy; the low foundation bearing capacity is higher than the high foundation bearing capacity.
