边坡支护结构岩土荷载计算若干问题

为计算不符合朗金条件和库伦条件的边坡支护结构岩土荷载,一些研究者提供了在经典土压力理论基础上扩展而成的岩土荷载计算方法。研究表明,这些方法在岩土荷载方向、在岩坡上填土时岩石坡面视为滑面的条件、考虑与不考虑地震力的岩土荷载公式之间的关系、地下水形成渗流时的土体荷载计算、有潜在滑动面边坡桩板式挡墙岩土荷载计算等方面存在一些问题,导致其实际适用范围明显缩小。

Several Problems in Geotechnical Load Calculation of Slope Support Structure

To calculate the geotechnical load of slope support structure which not accords with Langjin conditions and coulomb conditions, some re-searchers provide a few calculation methods obtained from the theoretical base of the classic soil pressure. The study shows that these methods have some problems in aspects like rock-soil load direction, slope surface as the sliding surface condition with soil refilling in rock slope, geotechnical load formula with/without consideration of earthquake force, soil load calculation when underground water forms seepage, and the geotechnical load calculation of plate retaining wall with slope piles and potential sliding surface. These existing problems obviously render its practical application range smaller.
