Based on the analysis of geological data and meteorological data of landslide, the mechanism of rainfall-induced landslides was analyzed, and the relationship between landslide and rainfall was further discussed, including the landslides and rainfall distribution, the relationship between landslide and frequency of rainstorm, and the time relationship between landslide and rainfall.The results show that the probability of landslide occurrence and the quantity of landslides have positive correlation with rainfall.The landslides mainly occur from May to September in which the monthly mean rainfall is large.Meanwhile, landslide occurrence is closely related to the characteristics of rainfall of that day and rainfall of early days.When the daily rainfall exceeds 50mm or 10 days accumulative rainfall exceeds 100mm, the landslide is prone to occur and the occurrence rate of the latter is higher.

软基水闸下游河道河床的抗冲刷能力较低，且水闸的泄洪水流条件较复杂，其泄洪消能防冲问题是工程设计和运行极为关心的问题。通过对水闸下游河道消能水位选取、消力池尾坎顶高程、池深、池长及下游海漫段布置等分析，得出了水闸下游消能工布置的优化方法。本文成果可供类似工程设计和运行参考。
某高速公路的路基设计标高为2.65～2.95m,该高速公路所经过的某运河河堤标高约为4.8m,由于公路主线的设计标高低于目前河堤标高、受客观因素影响,只能挖开河堤回填河道做公路路基,原有河道将无法满足泄洪及生态用水要求,因此,高速公路所涉的运河段需要改移(新开河).通过水工模型试验研究,优化了设计方案布置形式,节省工程投资.本试验研究成果,可为同类工程设计和建设提供可借鉴的经验.
