急骤加荷时粘性土地基中产生了孔隙水超压力,因此抗剪强度显著減低,而威协了地基的稳定性。本文簡略地介紹了民主德国已故教授J.奥特有关急驟加荷时粘性土的抗剪强度理論,并建议用圓柱滑动面假設,分別考虑內摩擦力和凝聚力的作用求地基的极限荷重。相应于內摩擦力部分的极限荷重建議用苏联高尔布諾夫-柏沙道夫和B.B.克雷契米尔的理论和图表,但須代入本文中的等代內摩擦角Φ值。相应 The pore water overpressure is generated in the viscous ground during the sudden loading, so the shear strength is significantly reduced, and the stability of the foundation is emphasized. This paper briefly introduces the theory of shear strength of cohesive soils when Dr. J. Ott, the late professor of the German Democracy Institute, was involved in the sudden loading, and proposed to use the cylindrical sliding surface hypothesis to consider the internal friction and cohesion respectively to find the ultimate load of the foundation. Corresponding to the limiting load of the internal friction part, the theories and diagrams of the Soviet Union’s Kolbnov-Bassdorff and B.B. Krekimir are suggested, but the equivalent internal friction angle Φ in this paper must be substituted. corresponding
