3、177公里。 根据招标文件本项目工程勘察设计共分3个设计合同段，其中第A3合同段新建主线路线长约58公里，主要位于德庆县和封开县境内。地处东经1112559至1115033，北纬231129至232932之间。肇庆属南亚热带季风气候。年平均气温21.2，1月份平均气温约12，7月份平均气温约28.7。怀集县北部山区冬季可见霜冻。年平均降雨量约1650毫米，主要集中在49月；年蒸发量1300毫米以上。无霜期310345天。早春多阴雨，夏秋受台风外围影响，晚秋有寒露风侵袭。年内主要气候特点：春季温暖多雨，为低温阴雨偏轻年景，有轻度的倒春寒现象；前、后汛期雨量偏多，“龙舟水”与热带气旋降水明显；强对

4、流天气频发，大风天气较多，局部地方出现龙卷风。测区位于封开县和德庆县之间，整段线路地处低山、丘陵区，并且植被茂密，交通不便利，为测量工作带来了极大的困难。2测区已有资料设计部门提供的1：2000地形图、A3合同段工作大纲、A3合同段首级控制及成果、A3合同段初步设计外业相关资料3技术依据1) JTG C10-2007公路勘测规范2) JTG/T C10-2007公路勘测细则4资源配置仪器设备和软件序号仪器、软件名称品牌型号标称精度产地数量1双频GPS接收机华测X9005mm+1ppm上海6台2南方灵锐825mm+1ppm广东6台3全站仪徕卡TCR1102C2瑞士2台4水准仪南方DL2007DS
