Problems solved by technology

On the other hand, the physical and mechanical parameters of rock and soil used in the calculation are also conventional parameters, without considering the acceleration of infiltration rate
In short, there is no scientific and reasonable calculation method for the safety factor of the Zhulin landslide in the typhoon area considering the coupling effect of wind load and rainstorm

Abstract

The embodiment of the present invention provides a method for calculating the safety factor of bamboo forest landslides in typhoon areas, comprising the following steps: obtaining calculation parameters of landslides; obtaining typhoon wind level, wind direction, rain intensity and duration parameters; determining the individuality of moso bamboo on the slope per unit area Calculate the comprehensive permeability coefficient of the slope; calculate the safety factor of the bamboo forest landslide under the coupled action of typhoon, storm and rain. The embodiment of the present invention provides a method for calculating the safety factor of the bamboo forest landslide in the typhoon area. In the calculation of the safety factor of the bamboo forest landslide in the typhoon area, the mechanical effect of the typhoon wind load is considered, and the change of the infiltration condition of the slope body caused by the wind load is considered, so that This makes the calculation of the safety factor of the bamboo forest landslide in the typhoon area more realistic and very suitable for practical use.

Description

technical field [0001] The invention relates to the field of geological disaster engineering, in particular to a method for calculating the safety factor of bamboo forest landslides in typhoon areas. Background technique [0002] Bamboo forests are widely distributed in the southeastern coastal areas of my country. Traditionally, it is believed that the existence of bamboo forest roots plays a favorable role in the stability of landslides, so landslides with bamboo forests are not easy to slide. However, through actual investigation and research, it is found that compared with bare slopes, bamboo forest landslides tend to slide more easily under rainfall conditions, especially when typhoons land. [0003] There are many typhoons landing in the southeastern coastal areas of my country every year, and typhoons and heavy rains induce a large number of geological disasters. After a typhoon lands, most of the landslides within its influence area are affected by the typhoon wind...
