Study On Waves Testing And Quality Control Technique For High Fill Ground-launched Of Fu Ning Port Engineering

In recent years, As water transportation development rapidly in southwest region, In the mountains and hilly region of port construction inevitably lead to a lot of high fill ground-launched foundation, The compaction quality directly affect the quality and Service life of the foundation. Now High fill foundation of port ground-launched compaction degree testing of traditional method have Sand filling method, nuclear measurement, ring knife method, etc, These methods are suitable for filling aggregate size is small, thickness thinner filling basis. So how effective evaluation of high fill base port ground-launched compaction quality has become a problem to be solvedIn this paper, the characteristics of engineering and waves propagation in the mixture of soil and stone are discussed on the bases of theoretical analysis and model experiments, Through the experiment summed up the empirical formula between the compaction of soil and stone mixture of high fill ground-launched port and shear wave velocity in it, And on this basis, Through the field experiment verified the testing technique of the mixture of soil and stone of high fill ground-launched is reliable, and let this technology applications though Practical engineering, It is found that the testing technique is practicable and reliable through putting it into practice. The main points are briefly summarized as follows:1. Through collecting the references both at home and abroad, Summarizes the development status of the technology now, And explains various technical construction control of the mixture of soil and stone.2. In order to establish the correlation model between shear wave velocity and compaction degree, Use the soil samples bring from the FuNing port scene that in Yun Nan, Making a batch of specimens which Density are not identical, And measured the shear wave velocity corresponding with each specimen respectively; Then we used four common curve models fitting analysis The relationship between them, And established the mathematical model between them.3. On the basis of work done before, Combination with engineering experience and Waves testing technique on compaction degree of the mixture of soil and stone Then use Waves testing technique about the soil-stone embankment, detected the mixture of soil and stone of FuNing port scene, and then evaluated the its compaction quality, The results of putting this technique to practice indicate that the remarkable success can be achieved on the integral quality of the soil-stone embankment.4. Testing models are applied to analyze the wave propagation characteristics and the method of compaction degree of the soil-stone embankment. Through on-site validation on FuNing port scene, compaction degree of experience formula is feasible.
