| 摘 要： | 对一种新型支挡结构即框架预应力锚杆支挡结构进行了研究.合理选取了框架预应力锚杆支挡结构的土压力计算模型和框架、锚杆的计算模型,并提出采用力法求解框架和锚杆的内力.改进了锚杆自由段长度的计算方法,推导了结构的基础埋深和稳定性极限平衡分析的计算公式.用此方法设计的多个高边坡经实践证明安全、可靠并具有良好的经济效益.此方法也为黄土边坡支挡结构计算提供了一种新的途径.

| Abstract: | A new type of supporting structure,namely the framed supporting with pre-stressed anchor bars,was analyzed and investigated in this paper.Rational calculation models of soil pressure,frame,and anchor bars were selected,and it was proposed that force method was to be used to calculate the internal forces of the frame and anchor bars.The calculation method for freedom length of the anchor bar is improved,and the calculation formulae of structural foundation embedded depth and stability limit equilibrium analyses were derived.It was witnessed by its utilization for designing several high loess slopes that there were higher safety and reliability and better economical benefit,so that it could provide a new way of calculation of supporting structures for loess slope. |
