一、刚性、柔性基础受力状态的演变(一) 刚性基础的概念刚性批础的理论剖面是梯形的,如图1所示.悬臂L在基底反力P作用下,对截面I-I形成弯曲和剪切作用.由于通常刚性基础L/H≤1,L段呈短悬臂块体,它对I-I的弯、剪作用不能用材料力学理论分析.对常见的毛石、砖、混凝土、灰土……等材料基础,通过试验或工程实践确定了其各自的
First, the evolution of the rigid and flexible foundation stress state (a) The theoretical basis of the rigid foundation concept rigid approval foundation is trapezoidal, as shown in Figure 1. Cantilever L under the action of the base reaction force P, forming a bend on the section II and Shear effect. Due to the generally rigid basis L/H ≤ 1, the L segment is a short cantilever block, and its bending and shearing action on II cannot be analyzed by material mechanics theory. For common rubble, brick, concrete, lime soil... And other material bases, which have been determined through tests or engineering practices.
