13、现在汛期的89月份或稍滞后些时间，低水位多出现在56月份。年水位变幅约23米。丽景华苑工程共计14栋住宅楼，我施工单位派驻四个项目部进行施工。3施工部署3.1 施工总体部署根据工程特点,本工程为地下工程，采用大开挖施工，基础在潜水层以下，因此需进行降水施工，降水方式为管井降水，具体布置详见丽景华苑项目部井点布置图。3.1施工总体流程施工准备（人员、材料、机具等，临水、临电及临设等）测量、放线、定位基坑土方挖运（分步进行）清槽底施工后续工程施工。3.1.1基本原则：将开挖现场分成四个区域从里往外，分两层进行开挖。开挖深度从自然地坪（绝对标高+20.000米）计算总计5.6米，挖土方量总计21.4
14、万立方米，回填9.67万立方米。首先用220型挖掘机将现场的建筑垃圾及红砂（深度1米）进行清除，再进行第二层开挖。待地下水位降至基坑底50cm以下后进行第二层开挖深度3.82米（绝对标高14.880米），最后用55型挖掘机进行桩间土的开挖，开挖深度0.5米，预留0.3米厚的浮土进行人工开挖与清理。3.1.2施工单位土方开挖进行分段，按照分区顺序进行开挖。详见附图：（根据现场主楼打桩顺序及土方运输方向进行土方开挖；土方运输第二、十四项目部由南向北进行运输，第八项目部由北向南运输，第十八项目部由东向西运输。4施工准备4.1技术工作准备4.1.1 组织施工管理人员认真学习施工图纸和设计方案，掌握施工
