Concealed Riprap Detection Technology In Pile Foundation Engineering, Li Junjie, Ge Longjin, Zhang Honggang, Li Jianmin, Zhu Honglei, Li Guanhao
Coal Geology & Exploration
It is often necessary to use pile foundation to deal with soft soil foundation for the newly built gate station near the seawall. If there is a concealed riprap layer in the construction area, it will affect the construction progress of pile foundation and increase the construction cost. Furthermore, the spatial distribution characteristics of riprap also play a decisive role in the selection of pile foundation construction technology. In view of the blindness problem in using the drilling method to investigate the irregular concealed riprap, we adopt the comprehensive investigation technology combining the ground penetrating radar with the high density …
Detection Accuracy Analysis Of Tsp And Its Application In A River-Crossing Tunnel Construction, Li Junjie, Zhang Honggang, He Jianshe, Rong Xin, Li Jianqiang, Guo Jiahao

Aiming at the problems of TSP such as long detection time and strong experience-depending, in order to improve the accuracy and the efficiency of TSP detection, we analyzed the key factors which affect data acquisition and processing accuracy of TSP and summarized the experiences of improving the detection efficiency of TSP. In combination with the TSP advanced geological prediction work in a river-crossing tunnel for water distribution project in Qiandaohu lake, the TSP tracing prediction or GPR detection in the area where the TSP resolution decreases were carried out and the geophysical abnormal area was verified by drilling. The results …
