Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, embodiment of the present invention is made below further
It is described in detail on ground.
Ultrasonic technology is widely used in industrial production and life, and the clear of petroleum pipeline is mainly used in engineering
Reason, sewage disposal etc., in treatment of soft foundation field or blank out.And it is many study show ultrasonic wave effect of vibration,
The glutinous effect of drop and cavitation can improve soil permeability.Therefore, ultrasonic applications are improved soft in treatment of soft foundation field
Base processing consolidation rate improves treatment of soft foundation quality, and engineering construction is had a very important significance.
A kind of method of the raising treatment of soft foundation consolidation rate based on ultrasonic wave, referring to Fig. 1, this method includes following step
Suddenly：
1) by the decay characteristics of ultrasonic propagation and the pitch-row of osculum 2, determine in ultrasonic treatment unit 3
The tranmitting frequency and power of ultrasonic probe 31；
The detailed operation of the step is：A certain amount of weak soil sample is chosen, two 31 correlations of ultrasonic probe are installed,
One is used as transmitting probe, and one is used as reception device, according to the amplitude A of transmitted wave0, received wave amplitude A, propagation distance x,
And ultrasonic attenuation formula：
I=I0e-αx
It determines attenuation coefficient α of the ultrasonic wave in weak soil, and then determines that the pitch-row of ultrasonic propagation osculum 2 is required
Ultrasonic wave tranmitting frequency ω and power.
Wherein, I is the ultrasonic wave sound intensity；I0For the initial sound intensity of ultrasonic wave；X is ultrasonic propagation distance；P is Media density；v0
For ultrasonic propagation velocity.
Meanwhile ultrasonic frequency is lower, and it is easier to generate cavitation.The frequency range 20KHz-40KHz generally used.
Ultrasonic wave tranmitting frequency and power are determined by single factors, it is necessary to consider ultrasonic wave attenuation coefficient simultaneously, osculum 2
The factors such as aperture and Soft Soil Layer moisture.Therefore Need Hierarchy Theory calculates and lot of experimental data finally determines.
