Special Engineering Properties Of The The Liupanshan Region Hard Soil And Soft Rock

The hard soil and soft rock is one kind of special weak rocky soil which in the Ningxia Liupanshan area highway construction often meets, it has the adverse effect to the road side slope stability. At present, domestic and foreign still was regarding this kind of weak crag earth characteristic research material rarely, adopted correspondingly the project measure also little mentioned. Development which along with the Ningxia Liupanshan area highway and railroad construct, does more thorough research to the hard soil and soft rock to appear extremely essential.In view of this present situation, this article widely is consulting the domestic and foreign related hard soils and soft rock processing technical paper in the foundation, unifies the Ningxia 101 provincial roads Shijing and Jingshuang the double road explorations the design the construction material, it has conducted more comprehensive research to the hard soil and soft rock project characteristic and the influence on stability of slope. And surveyed on the spot through the material investigation, has analyzed the Liupanshan area hard soil and soft rock formation reason, had pointed out the hard soil and soft rock expansibility weak wind resistant chemical property and so on the typical characteristic was major effect factor of its intensity. Based on this spot, has carried on the detailed analysis to the Shijing road hard soil and soft rock physics mechanical properties and the intensity characteristic, has carried out the system shearing strength experiment, obtains concerns shearing strength parameter of the Liupanshan area hard soil and soft rock under different ambient condition. It may supply when the hard soil and soft rocky ground district highway slope of cut stable analysis refers.This article has also carried on the analysis to the hard soil and soft rock slope of landslide characteristic. Pointed out the slope high the ratio of slope and the weathering depth is the hard soil and soft rock side slope stable major effect factor. And to the slope high, the ratio of slope and the weathering depth has carried on the numerical analysis, obtained between them the reciprocity. Those conclusions can instruct constructs to the Liupanshan area highway engineering.
