| 摘 要： | 以景鹰高速公路DK27+120里程附近滚石灾害防治为例，采用基于正交试验与运动学的滚石防护计算方法，对滚石运动学参数组合的优选以及防护结构设计控制指标的确定进行研究。将3类防护结构设计控制指标作为试验指标，将5种滚石运动学参数作为试验因素，应用正交试验表安排滚石运动轨迹数值模拟试验，进行3指标5因素正交试验。通过对试验结果的极差分析，找出最优参数组合，以此确定防护结构设计所需的指标值。对比该方法与概率分析2种方法的计算结果表明，在滚石运动学参数取值区间确定的情况下，本文提出的计算方法更直观合理、简便易行。

| Abstract: | Took the rockfall hazard near the DK27+120 section of the Jingying expressway for example,the kinematics combined with the orthogonal test was adopted to select the best combination of kinematic parameters and calculate the control indices for design of protective structure.Three control indices were taken as the testing indices,and five kinematic parameters were taken as the testing factors.The orthogonal test table was used to design twenty-five kinds of schemes,and the numerical simulation tests of rockf... |
