| Abstract: | The large scale construction of the underground car parking buildings and subsiding squares in our major cities has made the anti-uplift design a very critical problem.The key is to find the definition of the water level and the appropriate calculation of uplift pressure.The characteristics of the layered ground water conformations and seepage patterns,the relative relationship of the soil layers and the depth of underground structures are analyzed.Based on the experience of projects,the calculation method ... |
