Sinking control method for active control type open caisson construction
The invention discloses a sinking control method for active control type open caisson construction. The sinking control method comprises the following steps that 1, a sinking coefficient Kst and a sinking stability coefficient Kst, s are integrated into an active control sinking coefficient Kc; and 2, the well bottom soil body (103) is symmetrically partitioned, asymmetric partitioned excavation is conducted on all the symmetrically partitioned areas, uneven lifting pressure F is applied to the open caisson (100) during asymmetric partitioned excavation, and the active control sinking coefficient Kc is infinitely close to 1.0 all the time in the sinking construction process of the open caisson (100). The problems that in the prior art, an open caisson inclines, suddenly sinks and super sinks, the influence of open caisson construction on the surrounding stratum is large, and the construction progress is slow can be solved.
本发明公开了一种主动控制型沉井施工的下沉控制方法，包括以下步骤：步骤1：将下沉系数Kst和下沉稳定系数Kst,s整合为主动控制下沉系数Kc；步骤2：将井底土体(103)进行对称分区，对对称分区的各个区域进行不对称分区开挖，并在不对称分区开挖时对沉井(100)施加不均匀的提压力F，使主动控制下沉系数Kc在沉井(100)的下沉施工过程中始终无限逼近于1.0。本发明能够解决现有技术中沉井倾斜、突沉、超沉、沉井施工对周边地层影响大、施工进度慢等问题。
