一、安全系数不够,有倒塌危险的重大问题(1)小砖垛安全系数不够,实际安全系数2.0^-2.2。是由于计算不仔细,审查不认真造成的,如断面尺寸看错,不减木砖面积,断面面积小于0"35平方米而不提高安全系数,还有漏算荷载,底层计算高度取值过小等。总之都是由于对不利因素考虑不细造 First, the safety factor is not enough, there are major problems of collapse risk (1) small brick concrete safety factor is not enough, the actual safety factor 2.0 ^ -2.2. This is because the calculation is not careful and the review is not serious. For example, if the section size is wrong, the area of ​​the brick is not reduced, the area of ​​the section is less than 0”35 square meters without increasing the safety factor, and the calculation of the calculation value of the underlying calculation height. Too small, etc. All in all, due to consideration of unfavorable factors
