优化GPS测量软件系统的研制及其在岩土工程监测中的应用

为了提高GPS在岩土工程中的应用水平,研制了集GPS电子测量规范、适合多类型GPS接收机外业记录的电子手簿、岩土工程监测任务模拟软件和结果分析软件及岩土工程GPS监测网的优化设计于一体的面向岩土工程监测的GPS测量软件系统,并讨论了GPS网的基线重复性检核、同步环检核、异步环检核、坐标转换、网平差、GPS监测网的优化设计和形变量的显著性检验等关键问题.最后,通过对辽宁省抚顺地区的某矿区进行边坡变形监测的研究,验证了该软件系统不仅具有良好的实用性和可靠性,而且可以达到毫米级的监测精度,完全能够满足岩土工程监测的要求.图4,表3,参12.

Development of optimizing GPS surveying software system and its application in geotechnical engineering

To improve the application level of GPS technique in geotechnical engineering monitoring,a geotechnical engineering-oriented GPS software is developed,which integrated GPS electronic surveying criterion,electronic manual adapting to various GPS receivers for field record,GPS task simulation and result analysis software and optimizing design of GPS monitoring network.At the same time,pivotal problems such as check-up of baseline repeatability,check-up of synchronous closed-loop,check-up of asynchronous closed-loop,coordinate transform,network adjustment,optimizing design of GPS monitoring network and significance test of deformation variables etc.are discussed in this paper too.In the final,it is proved that the software has good feasibility and reliability,at the same time,the monitoring precision can reach millimeter order by processing GPS observation data with this software,which is able to satisfy the requirement of geotechnical engineering.4figs.,3tAbs.,12refs.
