土建工程师只有掌握了膨胀土地基上建筑物的变形特征、即膨胀土地基上建筑物变形破坏的特征,才能采取正确而有效的措施,进行膨胀土地基的变形计算,控制膨胀土地基上建筑物的实际变形值在其容许变形值范围之内,从而保证建筑物的抗裂安全性。膨胀土地基上建筑物因地基问题造成的开裂破坏与非膨胀土地基一样,是地基不均匀变形所造成的。不同的是,非膨胀土地基的不均匀变形主要是由于上部结构荷重和地基土的不
The civil engineer can only take correct and effective measures to carry out the deformation calculation of the expansive soil foundation and control the building on the expansive soil base only if he has mastered the deformation characteristics of the building on the expansive soil foundation, ie the characteristics of the deformation and destruction of the building on the expansive soil foundation. The actual deformation value is within its allowable deformation range, so as to guarantee the crack resistance of the building. The cracking damage caused by foundation problems on the building of an expansive soil base is the same as that of non-expanded ground, which is caused by the uneven deformation of the foundation. The difference is that the non-expanding deformation of non-expansive soils is mainly due to the failure of superstructure loads and the failure of foundation soils.
