| 英文摘要 | In many situations rock fall hazards cannot be eliminated because the occurrence of these hazards varies both spatially and temporally. Due to the high mobility of rockfalls, their intensity characteristics play important role in assessing their risk. This paper discusses a risk assessment methodology by taking the intensity information of rockfalls into account. A rockfall process modeling is performed to address such important intensity information as frequency-magnitude relationship, runout distance, kinetic energy, and the bouncing height of rocks. A grid computing methodology is developed to combine important intensity components of rockfalls for their risk assessment. A case study is conducted for risk assessment of rockfalls of Du-Wen Highway. The Due-Wen highway has been exposed to severe rockfalls hazard induced by Wenchuan earthquake. The risk assessment was performed on a section of Du-Wen Highway by combining intensity characteristics of rockfalls hazard and the vulnerability of highway transportation. Different rockfall scenarios have been taken into account involving combinations of various risks based on different types of consequences. Information on historical records of hazard events, frequency-magnitude and triggering mechanism provides additional insight to the recognition of risk sites and risk level. Further parameter calibration and expert judgment are required for practical risk management. © 2013 Taylor & Francis Group, London. |
