1、二、桩基础工程：1 工程简介1.1 工程简介本工程体育馆基础全部采用钢筋砼灌注桩基础，建筑桩基安全等级为一级，桩径500mm，桩端持力层选择层风化片麻岩，桩端全断面嵌入基岩不少于1m，主楼部分总桩数835根，门房部分桩基28根，总桩数863根。此外，本工程还包括单桩竖向抗压静载试桩9根，单桩水平静载试桩18根（其中包括反力桩9根）。1.2 设计要求1.2.1 桩身混凝土等级C35，纵向钢筋采用焊接接头，保护层厚度为70mm；1.2.2 试验要求：1) 桩正式施工前进行成孔工艺试验，数量不少于2个；2) 桩的承载力通过现场试验确定，具体要求为：桩的竖向抗压承载力通过单桩竖向静载荷试验确定，试桩数
2、9根，单桩竖向抗压极度限承载力标准值Qk=3300KN；单桩水平承载力设计值Rh=65KN；3) 检验桩身的质量和完整性采用动测法或其他方法，抽检数量不少于该桩数的20%；4) 现场试桩试验应满足建筑桩基技术规范（JGJ94-94）及其它有关规范的要求。5) 桩的最终承载力以现场试验为准，当试验结果满足计算值后方可施工下道工序。1.3 实物工程量钻孔灌注桩工程数量表 表7-1-2-1承台编号桩项标高岩层顶标高单桩长度（m）桩数（根）备注CT-1-T-6713.27086.76包括基础梁下桩基1根CT-1-T-7713.27077.76包括基础梁下桩基1根CT-1-T-9713.2706.58.
