4、代烟叶物流中心西面，紧临贵毕公路。该项目总建设规模8.4万平方米，用地面积134074平方米，建筑设计使用年限：50年。主要结构类型：全浇混凝土框架结构。建筑结构安全等级为二级。基础形式：孔桩基础。2.2本工程各参建单位建设单位：毕节市烟草公司设计单位：云南省建筑设计研究院勘察单位：深圳市勘察研究院有限公司监理单位：贵州宇建建设监理有限公司施工单位：贵州建工集团第四建筑工程有限责任公司2.3基础工程设计概况本工程共有孔桩450个，圆桩桩径为9001200mm，。孔桩最小间距为5.1m，桩端入岩深度不小于1.0D，孔桩护壁砼及填心砼标号为C30，护壁为倒挂式护壁，上口厚度为150mm，下口厚度5

5、0mm,（具体做法见附图）。桩端支承于中风化石灰岩，承载力特征值为4000KPa。 根据地勘报告显示：最长桩身30m，其中有200个孔桩深度超过16米（详见人工挖孔桩统计表）。根据住房和城乡建设部建质【2009】87#文件规定的“开挖深度超过16米的人工挖孔桩工程”，需要组织专家论证。 B1库人工挖孔桩统计表孔号地勘编号板底高程(M)持力层层顶高程(M)孔深(m)备注1ZK3631476.261481.767.6 2ZK3641476.311481.817.33ZK3651467.961473.4615.54ZK3661470.591477.1911.55ZK3671456.091461.79
