绪言
1 测绘的目的和任务
本次工程地质测绘的目的是通过运用地质学、第四纪地质与地貌以及工程地质学的相关理论知识通过现场踏勘以及现场原位试验对与尧山工程建设有关的各种地质现象进行观察和描述，初步查明大河乡-尧山地区拟建场地或各建筑地段的工程地质条件。将本测区的工程地质条件诸要素采用不同的颜色、符号，按照精度要求标绘在一定比例尺的地形图上，并结合勘探、测试和其他勘察工作的资料，编制成本地区工程地质图。这一重要的勘察成果可对大河乡-尧山建筑场地或各建筑地段的稳定性和适宜性做出评价。
本次实习踏勘线路由老师先拟定，并带领学生进行。整个过程由老师讲解、示范，使学生能够初步了解测区的地形地貌、水文地质现象、地质构造、物理地质现象、岩土体工程特征等工程地质条件的情况，并学会用罗盘进行仪器定点、岩性观测、鉴定和描述等内容和方法。
尧山地质测绘最终需要提交的成果包括尧山第四纪地质测绘综合报告、综合工程地质图、工程实际材料图、野外勘探记录表、 综合地质柱状图、工程地质剖面图，并对本测区的工程适用及地质特性提出工程地质评价。
2 测区的位置、范围和填图面积
测区地址位于桂林市东北郊左右董家巷周围，面积大致为4.6km2，北至大头岭到乌树岭、老虎岭一带，南起上东窑到阳家果园一带。西起漓江，东至朱家一带。
3 工程地质测绘方法及手段
本次实习主要采用的工作方法为路线穿越法、界线追索法、布点控制法三种，同时运用地质钻探，现场麻花钻取土观察等工程地质手段进行测区地质勘察。
4 测绘比例尺和完成任务的时间
按规范规定，工作手图的比例尺应大于提交成果图的比例尺，本次实习要求提交1:10000工程地质测绘成果以便保证测绘工作的精度。任务完成时间为期两周。前期老师带领团体同学进行踏勘，中期各小组自行组织完成此次野外现场踏勘，后期各同学进行室内资料整理，并编写实习报告。
