摘　　要：滑坡体的动态变形往往是在在滑坡体上布置多个传感器,属于多点综合观测,但是目前的分析仅依靠某个关键点进行评判,并未考虑仪器自身的因素,容易引起数据信息的流失。为了克服以上不足,开发了滑坡多点原位动态变形分析的MIFS系统,即多传感器智能融合反馈系统。系统采用数据级融合方法,将其应用于西南某滑坡动态变形的监测分析,融合后的数据较为理想,消除了融合前数据的矛盾性和不准确性,获得了被测对象的一致性描述和解释。经分析知:自监测之日起,该滑坡变形经历了缓慢变形期、匀速变形期、加速变形期以及急剧变形期等四个时期,这符合滑坡的工程特性依时性变化规律。工程实例证明了该系统在滑坡动态变形监测与反馈分析中具有有效性和可行性。Many sensors are arranged on landslide body in dynamic deformation, which is the multiplepoint comprehensive observation. But it only predicts the model on one key monitoring sensor at the same time with out considering the instrument itself, it caused the data information lost easily. In order to overcome the above shortcomings, a MIFS system applied in multiplepoint dynamic deformation analysis for landslide is devel oped, that is multisensor intelligent fusion feedback system. The system is applied in monitoring analysis for landslide dynamic deformation using the data fusion method, the data after fusion is good, and it eliminates the contradiction and inaccuracy of data before fusion . Finally, the results identified that the landslide had experi enced slowly deformation stage, uniform motion deformation stage, accelerated deformation stage and rapidly deformation stage, it accords with the law of nature. The engineering examples prove the effectiveness and fea sibility of the system in dynamic deformation monitoring and information feedback for landslide.
