摘要
在综合分析影响带立柱浅基础抗侧向倾覆机理与侧向抗倾覆稳定性的基础上,对立柱基础侧向的土体破坏模式进行了分析与研究,并基于极限分析原理,推导了带立柱浅基础的侧向极限承载力理论公式。将这些理论公式应用于工程分析,其结果相对现有规范公式相当理想,研究结果表明,推导过程所做的假设具有可信及可用性,该公式的推导结果对于工程实际应用具有较重要的价值。
The lateral failure modes of the foundations with columns are analyzed and studied by means of analyzing the lateral-overturning-resistance mechanisms and stability of the shallow foundations with columns. The theoretical formula for the ultimate lateral load-bearing capacity of the shallow foundations with columns is deduced on basis of the limit analysis principle. The theoretical formula is applied in the engineering analysis and the result, compared to the formula specified in the current specifications, is extremely satisfactory. The study indicates that the assumption made in the deduction is reliable and applicable and the result obtained by this formula is valuable for engineering practices.
