Problems solved by technology

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

Embodiment

[0044] A slope site needs to be leveled, and the surrounding excavated soil is dumped by a muck truck. During the construction process, by measuring the muck truck on site, it is determined that the distance l between the front and rear tires of the muck truck is 2.8m, and the width b between the tires on both sides is 2.5m; the weight of the muck truck itself G 0 is 48kN, the volume V of the muck truck filled with earthwork 0 10m 3 , the weight of earthwork in the vehicle γ 0 16kN / m 3 , it is determined that the total weight G of the muck truck when it is full of earth is 208kN; under a certain working condition, the slope height H of the soil slope measured by the level gauge is 5.0m, and the slope angle α of the slope is measured by the inclination sensor is 47°; take a typical soil sample from a soil slope on site, put it into a measuring cylinder, measure the volume and mass of the soil sample, and then convert its weight γ to 17kN / m 3 ; The typical soil sample is ca...

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...
