Method for predicting safe distance of soil dumping of slag truck at soil slope top

Abstract

The invention provides a method for predicting the safe distance of soil dumping of slag truck at a soil slope top. The method comprises the following steps: (1), determining the spacing l between front and rear tires of a slag truck and a width b between tires at the two sides; (2), determining the total weight G of the slag truck loaded with soil; (3), determining a height H and a slope angle alpha of the soil slope; (4), determining engineering properties, including a weight gamma, an cohesive force c, and an internal friction angle, of the soil of the soil slope; (5), determining a slide angle beta based on a Matlab computer program or trial algorithm; and (6), determining a safety distance L from the rear tire to the shoulder of the slag truck based on a formula. The method has advantages of simple use, good flowing performance and high result reliability.

Description

[0001] 【Technical field】 [0002] The invention relates to a method for predicting the safe distance of soil dumping by a muck truck at the top of a slope. [0003] 【Background technique】 [0004] In mountainous slope excavation and filling leveling projects, earthwork is often dumped on the slope. When this construction method is used, in order to reduce the workload of the bulldozer pushing the soil to the slope, it is often necessary to move the muck truck as far as possible. near the shoulder. However, since most of the dumped earthwork is in a loose state and its strength is low, if the muck truck is too close to the slope shoulder, under the additional pressure of the earthwork truck, it is easy to cause the soil under the muck truck to slide and become unstable, causing the muck truck to roll. Falling to the bottom of the slope will cause great danger to vehicle safety and personnel. [0005] When the muck truck dumps the earthwork, what is the safe distance from the s...

However, since most of the dumped earthwork is in a loose state and its strength is low, if the muck truck is too close to the slope shoulder, under the additional pressure of the earthwork truck, it is easy to cause the soil under the muck truck to slide and become unstable, causing the muck truck to roll. Fall to the bottom of the slope, causing great danger to vehicle safety and personnel

[0005] When the muck truck dumps the earthwork, what is the safe distance from the slope shoulder to prevent the earthwork from slumping? The method for predicting the safe distance of soil dumping by muck trucks on the slope top of the soil planting slope has the advantages of simple use, strong flow and reliable results
