西辽河是一条摆动河流，河流改道、河床下切、坍塌、兑岸现象难以控制，采用传统的方法险工险段始终没有得到根治。１９９３年以来，在该河上的敖吉、界力本、颜大坑、工农、苏家、后新立和靠山等７处险工采用软体沉排新技术，其主要措施是在设计枯水位以上采用无纺布反滤层，干砌块石护岸；在设计枯水位以下采用软体沉排，即由聚丙烯编织布加工成编织布排，在上面铺设铁丝石笼框格，框格内采用编织袋装砂压载，破冰沉入河底。软体沉排有较强的抗冲淘能力；具有整体性和连续性，经济耐用，使用效果较好。 West Liaohe River is a swinging river, diversion of the river, cut under the riverbed, collapsed, to shore the phenomenon is difficult to control, using the traditional method of risk insurance has never been radical. Since 1993, a total of 7 mechanics such as Aoji, Jieli Ben, Yan Dageng, workers and peasants, Su-house, post-Xinli and pawnshop have adopted the new technology of soft sinking technology. The main measure is to adopt above designed low water level Non-woven filter layer, dry block stone revetment; in the design of low water level using soft sink row, which is woven into woven cloth polypropylene braid row, laying in the above wire gabion box grid, the grid within the bag Sand loading ballast, ice immersed in the river. Soft sink row has a strong anti-scouring ability; with integrity and continuity, economic and durable, the use of better.
