- Abstract
Controlling construction speed is a key factor to ensure the stability of dam slope in soft groundsill. In this paper, for the construction of soft groundsill damming in Shuangwangcheng reservoir, a dynamic monitoring method of soft groundsill damming, considering the excess hydrostatic pore water pressure and anti-slide stability safety surplus degree of dam slope during the construction, was proposed. First, the real-time excess hydrostatic pore water pressure in soft soil layer during the construction was obtained by monitoring. Second, the real-time stability safety factors of dam slope during the construction was obtained by analyzing the stability of dam slope. Finally, according to the stress levels of excess hydrostatic pore water pressure and stability safety factors of dam slope during the construction, different monitoring and early-warning threshold values were set, then the construction safety level was evaluated and different monitoring control predetermined plan were employed to take different engineering measures to ensure the safety of dam. This method can ensure the stability of the dam foundation and improve construction efficiency, shorten the construction period and save the project cost.
