Only earth pressure and water pressure are usually considered for calculating lateral pressure of basement lateral wall and supporting structures. Nonconsideration of groundwater seepage is one of the main reasons why measured values of waterearth pressure on supporting structures are generally very different from those calculated values. Under the action of seepage, its force change the soil effective stress and affect the soil shear strength. Mechanical effects of groundwater seepage on earth pressure are researched and the hindering force and seepage force were considered together. By setti...
