桩基m值的影响因素复杂,而碎石土斜坡场地桩基m值的影响因素较水平场地又有所不同。为研究碎石土斜坡场地m值的影响因素,在现场单桩水平静载试验的基础上,根据现场实际情况用数值分析软件进行模拟,建立可靠的数值试验模型,并应用灰色关联度法分析6个重要因素对碎石土斜坡场地m值影响程度。研究成果表明,6个影响因素对碎石土斜坡场地桩基m值影响各不相同,按其影响程度的大小排序为桩前坡度>土体密度>桩长>嵌岩深度>桩截面特性>桩身材料。
The influencing factors of m value of pile foundation are complex, while the influential factors of m value of pile foundation in gravelly soil slope site are different from horizontal ground. In order to study the influencing factors of the m value of the gravelly soil slope site, based on the static static load test of the single pile in the site, numerical simulation software was used to simulate the actual situation of the gravel soil. A reliable numerical experiment model was established and analyzed by gray relational analysis Six important factors affect the m value of the gravelly soil slope site. The research results show that the influence of six influencing factors on the m value of pile foundation in gravelly soil slopes are all different. According to the order of influence degree, the order of the slope value of the pile is slope before slope> soil density> pile length> socketed depth> Pile material.
