Study on Soft Foundation Settlement Analysis and Treatment of Bridge-Head

摘要

In recent years, the construction of roads and bridges in China has been made remarkable achievements; the construction quality and road performance have been greatly improved. But the soft foundation settlement processing still prevents the quality of driving from improving. The improper handling of soft foundation settlement would result in vehicle bump at bridge head, and cause damage to the road surface of the bridge and telescopic device. On the principle of effective stress of the soil, a method is used to accelerate the foundation settlement in the negative pressure zone, and it has effectively reduced the differential settlement of bridge-head which improves the stability of roadbed.
