Abstract

The invention discloses a Phyllite artificial cut slope landslip early warning method featured by comprising the following steps: a, investigating field to plot a landslip body gradient [alpha], a landslip body area A, a landslip body upper side area Au and a landslip body upper side gradient [beta] of a phyllite region artificial cut slope; b, calculating a landform integral discrimination factorT of the phyllite region artificial cut slope according to T=S+1.8U; c, calculating an equivalent rainfall R* and a rainfall factor R; d, calculating a landslip determine value P; e, discriminating the conditions of the landslip determine value P and a landslip critical value Cr. The invention aims at the phyllite region artificial cut slope, studies internal mechanisms of landform factors and rainfall factors on the landslip forming degrees, fully considers phyllite region particularity and soil penetration characteristics, builds an artificial cut slope landslip early warning calculation model, determines the landslip early warning grades in a quantitative mode, and greatly improving the early warning accuracy.

Description

technical field [0001] The invention relates to the field of prevention and control of artificial slope-cutting and landslides, in particular to an early warning method and application of phyllite artificial-cutting slopes and landslides. Background technique [0002] The new slopes formed by artificial slope cutting are widely distributed in low mountain and hilly areas, especially in the eastern low mountain and hilly areas of our country. Due to the growth of people's income, the per capita living area has also been increasing. The original housing can no longer meet the growing living needs of local residents, and new buildings need to be built. But our country has less arable land, and to protect the arable land, if we want to build new houses, we have to find another way. [0003] The only way to consider is to form a new dwelling site by cutting slopes on the side of a low mountain. In order to reduce the construction cost, increasing the slope of the slope is the u...
