    • Abstract
  • The Benoto pile has been widely used in the piled foundation due to its advantages of no risks of breakage and reduction for piles, no collapse for holes and small disturbance to the surrounding buildings. The rapid public transport line No. 1 in Nanjing adopts this kind of pile. The site conditions, construction technology of the Benoto pile and difficult and important procedures for its construction are reported. The inclinometer holes located near the subway with the distance of 1.5~2.0 m to measure the horizontal deformation are driven, and the effect of the construction of Benoto pile on the horizontal deformation of foundation soils near the subway is analyzed. The measurements show that the maximum lateral deformation is 24.3 mm for the test section located near the subway with the distance of 1.5 m, which is less than the cumulative alarm value of 30 mm. Hence, it can be concluded that the construction of Benoto pile can effectively avoid the disturbance to its surrounding buildings.
