| 摘 要： | 以长条形基坑常用的带顶部支撑排桩支护体系为研究对象，同时考虑冠梁的影响，建立单元支护体系的能量计算式，利用最小势能原理，推导出单元支护结构中连接支撑的排桩底部位移和冠梁中部位移，由此得出整个支护体系变形表达式，并分析了主要参数对位移的影响。最后利用实际工程加以验证。

| Abstract: | The expression of the potential energy of the total piles in row with top brace retaining system in long strip foundation pit is established. According to the minimum potential theory, a solution to the maximum displacement of the top beam and the pile is derived. Then the expression of the piles in row with the top brace is given. The effects of the retaining structural parameters on the maximum displacement are discussed. At last, a practical example is presented. The calculated result is compared with the measured result. The comparison shows the method is feasible． |
