Comparative Study on Mechanical Property of Photovoltaic Support Foundation in Waste Dump Side Slope
Side slope area has special engineering geo-logical characteristics.At present,there are few studies on the foundation type of photovoltaic support in such areas.In this paper,the interaction between pile and soil and the stress distribution of pile body under horizontal load are studied for two types of foundation of single pile and dou-ble-row single pile connected in the slope direction.The results show that under the horizontal load,the maximum displacement of the soil around the pile in the single pile foundation type appears at the top surface of the slope on the right side of the pile body,and the maximum stress of the pile body appears at the bottom of the pile;in the double-pile foundation type,the maximum displacement of the soil around No.1 pile appears near half of the depth of the pile body into the earth,and the stress distribution of the pile body is relatively uniform,the maximum dis-placement of the soil around No.2 pile appears at the top surface of the slope on the right side of the pile body,and the maximum stress of the pile body appears at the bottom of the pile.
