Abstract
Aiming at the problem that the traditional core drilling detection method has certain damage to the impervious body, and the detection points are limited, which leads to the limitation of the evaluation results; this paper proposes a detection method of seepage control effect of building stress wall structure based on transient Rayleigh surface wave method. The wave velocity of Rayleigh wave under plane stress is obtained by combining wave equation with plane stress. Under the three boundary conditions, it is theoretically feasible to detect the cutoff wall with transient Rayleigh surface wave technique. Therefore, based on the transient Rayleigh surface wave theory, the 24 channel broadband signal input channel and the minisis24 integrated engineering detector with advanced computer are used as the carrier to detect the anti-seepage effect of the stress wall structure. The practical engineering test shows that the permeability coefficient of the wall measured by this method is in good agreement with the core drilling method, and it is a reliable non-destructive testing method for wall anti-seepage.
