The invention discloses a method for monitoring rammed point soil stabilization state vibration in real time. The method comprises the two steps of trial ramming and construction. According to the step of trial ramming, a trial rammed point is selected, a measurement line and a monitoring point are arranged, a vibration pickup and a collecting and recording device are arranged, forced-ramming vibration of the monitoring point is observed, back analysis is carried out on the rammed point soil vibration, characteristic parameters of the rammed point soil vibration are obtained, soil of the rammed point soil is extracted to be tested, rammed point soil stabilization state parameters are obtained, a quantitative relation between the characteristic parameters of the rammed point soil vibration and the rammed point soil stabilization state parameters is set, and monitoring criteria of the rammed point soil forced-ramming stabilization state vibration are set. According to the step of construction, a forced-ramming vibration monitoring system is arranged, forced-ramming vibration is monitored, back analysis is carried out on the rammed point soil vibration, and the rammed point soil stabilization state is judged according to the monitoring criteria of the rammed point soil heave-ramming stabilization state vibration. The method for monitoring the rammed point soil stabilization state vibration in real time can improve efficiency and accuracy for monitoring the rammed point soil stabilization state, and lower the construction cost.
Description
technical field [0001] The invention relates to the field of foundation reinforcement, in particular to a method for real-time monitoring of vibration in the state of soil reinforcement at ramming points. Background technique [0002] Dynamic consolidation, English called Dynamic consolidation, that is, dynamic consolidation, was first created by French engineer Menard in 1969, and was introduced in detail through literature in 1975. When strengthening the foundation with dynamic ramming, hoist the 8-30t (about 80-300kN) rammer to the air of 6-40m, and then let the rammer fall freely to hit the ground, generating a huge stress wave in the soil and reorganizing the soil structure Compaction, so as to improve the bearing capacity of the foundation and reduce the compression deformation of the foundation. [0003] The construction of the dynamic compaction method is simple and easy, the reinforcement effect is good, the material is saved, the application range is wide, and the...
