本文分析了盐渍土的遇水湿陷等特性,介绍了钻孔压浆桩在盐渍土地基中的施工工艺及特点,通过青海花土沟地区三个建筑物桩基础的施工试验,证明钻孔压浆桩适于作盐渍土建筑基础。其桩径、桩长均可调,施工工艺简单,人工、材料消耗少,造价要比其它建筑基础低30%~50%。
This paper analyzes the characteristics of water-sagging and sinking of saline soils, describes the construction process and characteristics of drilling grouting piles in saline soils, and proves that the construction of pile foundations of three buildings in the Huatugou area of Qinghai Province proves that Bored grouting piles are suitable for the foundation of saline soil. The pile diameter and pile length can be adjusted, the construction process is simple, and the labor and material consumption are low. The construction cost is 30% to 50% lower than other building foundations.
