Design method of non-uniform foundation derrick foundation structure
The invention provides a non-uniform foundation derrick foundation structure design method which comprises the following steps: determining engineering geological conditions according to geotechnical engineering exploration, and identifying the thickness of a rock-soil layer and the bearing capacity of a foundation; the foundation structure types of the cast-in-place piles and the raft are determined, the vertical bearing capacity of a single pile is calculated, and the replacement rate and the pile number are determined; calculating the length of a cast-in-place pile according to the thickness and burial depth of the non-uniform stratum and designing pile arrangement; carrying out settlement checking calculation on a composite foundation formed by the cast-in-place pile and the surrounding rock-soil layer; determining a hole forming mode and a pile forming mode of the cast-in-place pile according to rock and soil conditions; manufacturing and installing a cast-in-place pile reinforcement cage, pouring concrete and waiting for setting, arranging a reinforced concrete bearing platform at the top of the cast-in-place pile, and integrally serving as a drilling derrick foundation.
本发明提出了一种不均匀地基井架基础结构设计方法，包括：根据岩土工程勘探确定工程地质条件，识别岩土层厚度及地基承载力；确定灌注桩及筏板基础结构型式，计算单桩竖向承载力，确定置换率、桩数；根据不均匀地层厚度及埋深计算灌注桩长度及布桩设计；对灌注桩及与周围岩土层形成的复合地基进行沉降验算；根据岩土条件确定灌注桩的成孔和成桩方式；灌注桩钢筋笼的制作与安装、混凝土浇筑及候凝，灌注桩顶部布设钢筋混凝土承台，整体作为钻井井架基础。
