区域重力调查中重力基点网定额制定工作探讨

摘要

This paper focuses on investigating the amount of work, gross expenditure, staff input, and working hours with regard to gravity base-point net connection surveying which is involved in the scale of 1:250000 or 1:200000 regional gravity survey projects of 21. These projects were scheduled for implementation by China Geological Survey in the last 6 years. On this basis, it makes a statistical analysis of the total cost, the total number of base points, and ifeld survey of each gravity base-point cost required with regard to gravity base-point net connection surveying. In accordance with the measurement results of actual costs that arises from the gravity base-point net connection surveying of 1:250000 map of Menyuan and Shandan regional gravity survey projects in Qinghai province, this paper suggests that if the regional coefifcient is 1, budgeted standard for each gravity base-point be 16500 yuan.%通过对近6年来中国地质调查局安排实施的21个1∶25万（或1∶20万）区域重力调查项目中重力基点网联测的工作量、总经费、投入人员及工作时间等项目的调研，对重力基点网联测总费用、基点总数、每个重力基点野外测量所需费用进行了统计分析。根据青海1∶25万门源幅山丹幅区域重力调查项目中重力基点网联测工作实际费用测算结果，建议在地区系数为1的情况下，每个重力基点预算标准为1.65万元。
