摘　　要：重力垂直梯度测量在地球物理勘探中发挥着重要作用。通过测量实验,快速准确计算出重力垂直梯度值尤为重要。目前测定重力垂直梯度的方法有两种:传统测定法、同步观测法。针对重力垂直梯度测量进行需求分析,采用这两种重力垂直梯度解算原理,设计开发一款基于Android平台重力垂直梯度解算软件,其具有采集数据记录、数据处理、限差检验、精度评定和数据查询功能。最后,通过实地重力垂直梯度测量试验,对该软件进行运行性能和结果可靠性验证,并对比两种解算方法的精度。试验证明,该软件的两种解算方法都能够满足重力垂直梯度测量精度要求。Gravity vertical gradient measurements play an important role in geophysical exploration.By measuring experiment,it is particularly important to calculate the gravity vertical gradient values quickly and accurately.Currently,there are two methods of measuring the vertical gradient of gravity：the traditional measuring method and the synchronous observation method.This paper,for the gravity vertical gradient measurement,by these two solving principles of gravity vertical gradient,designs and develops a calculation software based on the Android platform,which has collected data recording,data processing,tolerance test,precision evaluation and data query functions.Finally,by the gravity vertical gradient measurement test,it checks the performance and the reliability of the results of the software,and compares the accuracy of two solution methods.Tests show that the two solution methods of the software are able to meet the accuracy of gravity vertical gradient measurement.
