Study on the performance-proof-test method of an energy absorption type rockfall guard fence and its design method

高能型岩栅栏的性能目前取决于基于累积能量和可吸收能量的设计方法，这些方法是根据制造商的原始实验方法及其实验值进行评估的。本研究旨在改进高能型岩栅的模拟技术。实验和分析表明，即使落石能量相同，岩石栅栏的质量、形态和速度等落石特性也会影响岩石栅栏的性能，用累积规律来评价高能岩石栅栏的性能是不合适的。

The performance of a high energy type rock-fence is now depending on the design method based on the cumulative and absorbable energies which have been evaluated from a manufacturer's original experimental method and its experimental value. Improvement in a simulation technique of a high energy type rock-fence was aimed in this study. It has been made clear from experiments and analyses that the rockfall characteristics, i.e., mass, configuration and velocity, etc. influence the performance of a rock-fence even if the rockfall energy is same, and that the cumulative rule is unsuitable for evaluating a performance of a high energy type rock-fence.
