问题:在超长地下室自防水混凝土板设计中,经常会发生结构设计考虑不周,如钢筋用量不足、配筋错误、地基不均匀下沉、过度震动等,从而使混凝土拉应力过大产生裂缝。另外需要指出的是,一些工程设计突破了规范规定后,地下室墙的水平钢筋仍按构造配置,这也是墙较易裂缝的又一因素。 Problem: In the long basement self-waterproofing concrete slab design, structural design considerations often occur, such as the lack of steel reinforcement, reinforcement errors, uneven foundation subsidence, excessive vibration, so that the concrete tension is too large to produce cracks . In addition, it should be pointed out that some engineering design breaks through the norms and regulations, the basement wall of the horizontal reinforcement is still configured according to structure, which is more susceptible to cracks in the wall another factor.
