本文主要对PCM编码式的布设模式进行分析和改进,介绍PCM编码式和闭锁深度倍数式2种站点布设模式,然后在最小有效距离(MED)为6.31倍断层闭锁深度的情况下,通过精度评价方法对比2种布设模式的结果,发现二者相差不大。进一步研究MED的合理选择,结果表明,MED取20倍的闭锁深度比6.31倍的闭锁深度更为合理。在MED为20倍的情况下对比研究PCM编码式和常规闭锁深度倍数式布设模式的优劣,结果表明,PCM编码式的布设模式优于常规模式。将PCM编码式的布设模式应用于川滇地区的巧家-东川剖面进行检验,发现PCM编码式的结果优于目前站点分布得到的结果,说明合理的站点布设可得到精度更优的结果。本文研究对于断层形变监测中精确获取形变参数具有重要意义。"/>  We analyze and improve the layout of the PCM model. First, we introduced the PCM and the locking depth multiple models. Then, when the minimum effective distance (MED) is equal to 6.31-fold, we compare the results of the two layout modes by the accuracy evaluation method. The results are not much different. We study the optimal selection of the minimum effective distance (MED), then evaluate the advantages and disadvantages of the PCM model and the locking depth multiple layout model. The results show that the 20-fold locking depth of MED is more reasonable than the 6.31-fold locking depth. In the case of 20-fold locking depth in MED area, the PCM model layout mode is better than the locking depth multiple model. The PCM model layout model is applied to the Qiaojia-Dongchuan section of the Sichuan-Yunnan region for inspection. The results show that the results of the PCM model are more accurate than those obtained from the current sites distribution. The research is of great significance for accurately obtaining deformation parameters in fault deformation monitoring."/> 对PCM编码式GPS站点布设模式的评价和改进
