大同某矿井架桩基设计计算探讨

Discussion on design and calculation of derrick pile foundation in Datong mine

某矿副井井架,场地地基土自上而下为杂填土,湿陷性粉土,粉质黏土,强风化泥岩,因与之相邻的提升机房采用换填法处理地基,垫层底标高-11.200,且已施工,为减少井架基础施工对提升机房地基的扰动,经过计算,井架采用干作业钻孔灌注桩基础能保证井架的安全性、稳定性。

During derrick,a mine site for miscellaneous fill,from top to bottom of foundation soil collapsibility silt,silty clay,strongly weathered mudstone,due to the ascent of the adjacent room in filling method is used to deal with the foundation,cushion bottom elevation of-11.200,and the construction,to reduce the number of headframe foundation construction of hoist house foundation disturbance,after calculation,derrick of dry drilling filling pile foundation can guarantee the safety and stability of the derrick.
