超厚细砂层地质条件下钻孔灌注桩泥浆指标控制

A Study on Mud Index Control of Cast-in-Place Drilling Pile Under the Geological Condition of Super-thick Fine Sand Layer

根据淠河特大桥钻孔灌注桩细砂层较厚的地质特点,通过试验确定了相对密度、粘度、含砂率等控制指标,以指导施工,并取得了成功.

According to the geological character of thicker fine sand layer of cast-in-situ bored pile for Pi River extra large bridge, the relative density, viscosity and sand content which control the construction has been made by test and it has been successful.
