加筋碎石桩极限承载力的计算图式研究

Investigation on Ultimate Bearing Capacity Calculation of Reinforced Stone Pile

以加筋土强度理论和Brauns的单根碎石桩的计算图式研究理论为基础,提出了拉力破坏和粘着破坏两种破坏型式情况下的极限承载力计算图式,为实际工程设计提供依据。研究表明加筋碎石桩可大大提高软弱地基的承载力。

Based on reinforced-earth strength theory and single stone column analysis computation theory, the computation formula of ultimate bearing-capacity about tensile failure and adhesion failure was concluded. The research shows that the reinforced stone column can increase the bearing capacity of soft subgrad greatly.
