The Accumulation Layer Of Expansive Soil Landslide Micro Pile Technology Optimization Design Research

With the development of society and the progress of science and technology. Human understanding more and more attention in the living environment. Especially in our country since entered comparatively well-off society.Now the material conditions of life is getting better and better.The country began to pay attention to improve the personal and property safety of people.Therefore, the prevention and control of geological disasters in mountainous areas pay more and more attention.In the west of our country as the elevation above sea level ascension,the mountain area is wide, Accompanied by a landslide, Geological hazards such as earthquake and landslide is more and more serious, because of its high occurrence, damage effect become the extensive concern of social problems.Especially in the area of our province, every year by the landslide impact, local residents personal and property safety can not be guaranteed.The landslide and more for the expansive soil landslide.This kind of slide because of the special nature of the soil, encounter water swelling, shrinkage characteristics of drought.The mechanism of landslide is relatively complex, the harm is great, and difficult to control.Experts and scholars at home and abroad advanced technology,Especially in the recent ten years mini pile technology because of its convenience, cost less than the traditional support, widely used,But for this kind of landslide research means of governance is still in the exploratory stage,On the micro pile in landslide control mechanism is still in the research stage,There is no industry standard clear can reference management.Successful case most of the means of landslide control or reference at home and abroad were analyzed to design management,some schemes are not applicable to the special landslide.Optimization of the traditional method, can improve the treatment effect, reduce the cost of governance and other benefits.In determining the parameters of soil landslide thrust, the standard gives the reasonable design method,But in the pile spacing, the micro pile row spacing,and pile length has not yet identified reasonable numerical,This literary grace by physical model test, combined with field monitoring data, optimization design of micro pile, improve the micro pile design knowledge.Especially in the rainfall condition, seismic condition, applying this two kinds of boundary conditions on the micro pile, reflect a reasonable numerical micro pile parameters.
