Abstract

The invention discloses a county-area collapse geological disaster comprehensive treatment scheme type selection studying and judging method, which adopts a sequential flow method to conduct type selection studying and judging. The core process comprises four stages, namely firstly carrying out preliminary intention bottoming of masses, determining subsequent steps according to whether the masses support, secondly carrying out construction condition evaluation, utilizing a comprehensive index method to quantitatively analyze indexes such as traffic conditions, toe distances, slope cutting gradients and the like, dividing the construction conditions into 'complex', 'medium' or 'simple', then carrying out comprehensive judgment, carrying out layered treatment according to the construction conditions, namely carrying out coupling judgment measures based on vulnerability of disaster-bearing bodies and risk of hidden danger points when the construction conditions are 'complex', carrying out comprehensive decision based on treatment difficulty and threat degree when the construction conditions are 'simple or medium', and finally carrying out mass intention rechecking and dynamically feeding back the masses. The method effectively improves the accuracy and operability of the pattern selection of the collapse geological disaster treatment scheme, and reduces the resource waste and risk.
