【摘要】In this paper, we choose the Beijing Metro Line 6 as the study area. The land subsidence is obtained by using PS-InSAR technique, and the spatial distribution characteristics of subsidence in the study area are analyzed. We further combine hierarchical entropy method to locate the typical section of Line 6. The severity and uneven of subsidence is also analyzed. The main conclusions are as follows:(1) The rate of subsidence from west to east along the line 6 is gradually increasing, and annual maximum subsidence rate is 77.2mm/a, which appears in the ChangYing-CaoFang section; (2) The integrated entropy is divided by the JinTaiLu Station, the west side has a small entropy (less than 0.5), and the east side is close to 1 or greater than 1. The subsidence of the east side of JinTaiLu Station is serious. It is pronounced uneven subsidence. (3) In the three sections of JinTaiLu- ShiLiPu, QingNianLu- DaLianPo, HuangQu- CaoFang, the subsidence severity is affected by the annual subsidence rate, slope, curvature radius, and the correlation is strong.%本文以北京市地鐵6號線為研究區(qū),采用PS-InSAR技術(shù)對研究區(qū)53景Terra SAR影像進(jìn)行永久散射體干涉處理,獲取了研究區(qū)地面沉降信息,初步揭示了線狀研究區(qū)的地面沉降空間分布特征,進(jìn)一步結(jié)合層次熵值法,定位6號線典型路段,深入分析了地面沉降發(fā)展的嚴(yán)重程度及不均勻性.研究結(jié)果表明:①6號線沿線自西向東沉降速率增大,最大年沉降速率為77.2 mm/a,出現(xiàn)在常營—草房路段;②綜合熵值以金臺路站為分界,西側(cè)熵值小(小于0.5),東側(cè)接近或大于1,金臺路以東路段沉降量大,且不均勻沉降嚴(yán)重;③在地質(zhì)條件相似的金臺路-十里堡、青年路-褡褳坡、黃渠-草房3個(gè)路段內(nèi),沉降嚴(yán)重程度同時(shí)受年沉降速率、斜率、曲率半徑變化驅(qū)動(dòng),且相關(guān)性強(qiáng).
