为分析水平力作用下框架码头桩侧向土压力的分布规律,通过土质岸坡框架码头模型试验,分析了一定水深条件下在水平推力作用下桩前后侧向土压力沿深度方向、水平方向的分布规律,探讨了框架码头土体岸坡潜在滑动面的位置。结果表明,各桩的桩后侧向土压力比桩前侧向土压力大;同一根桩上,随着距桩底距离的增加,侧向土压力呈先增大后减小再增大的趋势;随着距坡顶水平距离的增加,桩后侧向土压力呈倒“~”变化趋势变化,桩前侧向土压力呈“~”趋势变化。这为工程实践中框架码头岸坡的受力变形特性提供了参考依据,具有一定的现实意义。
In order to analyze the distribution law of lateral earth pressure of frame pier pedestal under horizontal force, this paper analyzes the lateral earth pressure along the depth direction and horizontal direction under the condition of certain water depth under horizontal thrust Distribution law, discussed the location of the potential sliding surface of the soil quay slope. The results show that the lateral earth pressure of each piles is greater than the lateral earth pressure before piles. On the same piles, the lateral earth pressure first increases, then decreases and then increases with the increase of the distance from the bottom of piles. With the increase of the horizontal distance from the top of the pile, the lateral earth pressure at the rear of the pile changed in the opposite direction and the lateral earth pressure in the front of the pile changed in the direction of “~ ”. This provides reference for the mechanical deformation characteristics of frame wharf in engineering practice, and has certain practical significance.
