摘要
现行的土钉支护安全监控采用"终点控制"的方法,在实际工程应用中具有一定的局限性。针对这种情况,提出了土钉支护结构水平位移安全监测"过程控制"的概念,建立了双曲正切函数的过程曲线,旨在对土钉支护结构施工全过程做到安全有效的监测和控制,并将所建立模型与理正岩土计算软件的结果进行比较,较好地符合计算结果。
The ＂result control＂ method for safety monitoring of soil-nail retaining structure in present national code has some limitations in practical construction. Aiming at this, this article proposed the ＂process control＂ method and established the process curve based on hyperbolic tangent function. According to the method, the SONFOPIRS horizontal displacement development is limited in the security trace-control curve from beginning to end, so that the accumulated horizontal displacement is controlled in one threshold parameter. Besides, the article also made a comparison between this method and the LIZHENG software, the result was satisfactory.
