Influence of erosion voids and traffic loads on buried large-diameter reinforced concrete pipes
《Underground Space》2024年第4期120-131,共12页Ming Xu Dawei Shen 
financial support received from the National Natural Science Foundation of China(Grant No.51978382).
Geotechnical centrifuge tests were conducted to examine the influence of invert voids and surface traffic loads on 1400 mm diameter reinforced concrete pipes buried with a shallow soil cover depth of 700 mm.Void forma...
