Forecast and Suggestion of Research on Settlement Calculation

Settlement calculation of deep foundation of super high-rise building is a critical topic for construction engineering. Due to the complexity of geology and geological soil (tri-phase object), the difference with theories, calculated settlement results hardly comply with measured data, and there has’t been any satisfactory formula for settlement calculation, especially for deep foundation, such as box-raft foundation, single pile and pile group foundation. In China, the difference between calculated value and measured data is modify by applying a unified empirical coefficient. This method is admittedly to have the minimum variance of all the settlement calculation methods at present. However, there is so tremendous differentce with the geological condition of each region of China and so great differentce with regional soil characteristics, that calculation result is basically unsatisfactory. Is might be more close to the real condition to apply the regional empirical settlement formula.
