摘要
重力式基础的抗倾覆性能对于保证高耸结构的安全使用非常重要,而基础的倾斜计算是抗倾覆设计的一项重要工作。采用传递矩阵法对重力式基础的倾斜进行了计算和分析,并分别分析了倾覆力矩、基础尺寸和地基变形模量对基础倾斜的影响。计算结果表明,增大基础宽度和地基变形模量均可提高基础的抗倾覆性能。
The anti-overturning performance of gravity foundation is important to the safety of high-rising structure, and the inclination calculation is an important work in anti-overturning design of foundation. The transfer matrix method is applied to calculate and analyze the inclination of gravity foundation. The impact of factors, such as overturning moment, foundation size and deformation modulus of ground soil, on the inclination of foundation is analyzed. Calculation shows that increasing both the width of foundation and the deformation modulus of ground soil can improve the anti-overturning performance of foundation.
