摘　　要：经过长年的工程实践与理论探索,提出了摩擦桩单桩承载力来源于地心引力的观点,以地球引力场理论为基础,分析了摩擦桩桩周土与桩间的相互作用过程,揭示了摩擦桩单桩竖向承载力的确切机理,给出了基于地心引力的摩擦桩单桩竖向承载力计算原理与方法,阐述了基于地心引力的摩擦桩单桩竖向承载力计算过程和关键技术要点,通过一个应用实例揭示了基于地心引力的摩擦桩单桩竖向承载力计算方法的实际效果。Through engineering practice and exploration in terms of theory all the year round, it is put forward that the vertical load-bearing capacity of single friction pile originates the terrestrial gravity. Based on the theory of the gravitational field of the earth, the action between body of friction pile and soil around the pile is analyzed. The paper brings to light the precise mechanism of the vertical load-bearing capacity of single friction pile, giving the principle and method to calculate the vertical load-bearing capacity of single friction pile based on terrestrial gravity. The paper also expounds the calculating process and key technical main points of the vertical load-bearing capacity of single friction pile based on terrestrial gravity. The actual effectiveness of the vertical load-bearing capacity of single friction pile based on terrestrial gravity has been revealed by an actual example.
