Model Test of Rectifying and Reinforcing the Slanting Buildings on Collapsible Loess by Using the Expansive Method

Slauting buildings can always be found in collapsible loess regions because of the improper ground treatment. The ununiform sedimest of the foundations and the inclination of the upper-structures will bring about great dangers. First the calculation of the amount of expanding materials is made, based on interspaces which need to be compressed so as to rectify and reinforce the slanting buildings by using expansive method. Then the method and details of the model test are described . Finally the discrepancies between the results of model test and the theoretical calculations are discussed. But they are basically matched with each oterh, so the theory is proved to be true. It lays a theoretical foundation for slanting buildings on collapsible loess and can be used for references for engineers.
