| 英文摘要 | Debris flows often cause catastrophic damage to communities in the downstream area, by direct impact and deposition. Theoretical predictions of impact pressure and volume of discharge, however, still remain very challenging, mainly due to inadequate understanding of the complex problems and limited field data at the local scale. In this study, the maximum impact pressure (P-max) and total discharge (Q(total)) of 139 debris flow events that occurred during 1961 and 2000 in the "debris museum" of China (i.e., the Jiangjia Ravine) are reported and interpreted with statistical tests and probabilistic analyses. Four common probabilistic models (Normal, Lognormal, Weibull and Gamma distributions) are used to simulate the distributions of P-max and Q(total). The level of fitting of each model is assessed by performing two quantity-based statistic goodness-of-fit tests (Chi-square and Kolmogorov-Smirnov tests). The field data show that during the period from 1961 to 2000, the maximum values of P-max and Q(total) are 744 kPa and 1,751,537 m(3), respectively. It is suggested by the goodness-of-fit tests that the Weibull distribution is the only model (among the four probabilistic models) that is able to capture the distributions of P-max and Q(total) of both surge and continuous flows. Using the verified Weibull distributions and Gaussian copula approach, univariate and bivariate exceedance probability charts considering P-max and Q(total) are developed. Regression models between P-max and Q(total) are also established. (C) 2014 Elsevier B.V. All rights reserved. |
