摘要
利用一种新的分析方法 FRAM-SBAS时序分析方法,对兖州地区的ALOS PALSAR数据进行分析,研究该地区的高速公路沉降。FRAM-SBAS时序分析方法是一种融合了多种In SAR误差源校正方法的短基线集时序分析策略。利用Envisat数据,使用FRAM-SBAS时序分析方法获得的济宁地区在2008-09-21~2010-07-18期间地表的时序变化,得到了很好的研究结果,济宁地区最大时序沉降量为60 mm,最大沉降速率达到50 mm/a。高速公路路段最大沉降量达到53 mm,最大沉降速率为32 mm/a。而且高速公路沉降严重的路段均在地面沉降严重的区域,从而证明了矿区开采和车辆载荷对高速公路沉降的影响,同时也证明了该时序方法在地面及高速公路沉降监测方面的可行性。
        A new analysis method is used to analyze the PALSAR ALOS data in Yanzhou area,and to study the FRAM-SBAS data in this area.FRAM-SBAS timing analysis method is a kind of short baseline set timing analysis method which is combined with a variety of In SAR error source correction methods.Using Envisat data,use FRAM-SBAS timing analysis method to obtain the Ji'ning area in 2008-09-21 ~ 2010-07-18 will during the surface changes in the timing of the obtained good results,the Ji'ning area maximum timing settlement of 60 mm,the maximum settlement rate reached 50 mm/a.The maximum settlement of the highway section is 53 mm,the maximum settlement rate is 32 mm/a.And the settlement of highway worst sections were in severe ground subsidence,thus proving the mining and vehicle load effect on settlement of highway.And it is proved that the timing method on the ground and highway subsidence monitoring is feasible.
