Application of Pine Piles for Strengthening High Slope Channel Retaining Walls on Soft Soil Subgrade

Abstract:

In the modification of narrow deep soil channels of early urban excavation, because of great depth and steep slope, the gravity retaining wall slope will be needed. The problems of soft soil subgrade treatment at channel bottom have to be solved. Combined with the old channel treatment project of a city, as practical example, the method by which the soft subgrade of channel retaining walls strengthening with pine piles, is described. By application of Coulomb Theory, the stability calculation for gravity pitch-up oblique retaining walls is conducted. The results show that using pine piles is a good method for strengthening the soft soil subgrade with small thickness below the water level.
