国内外加固处理软土地基的方法很多,如换填法、强夯法、水泥搅拌桩、压密注浆、硅化加固地基、碎石桩等。就其适用范围而言,水泥搅拌桩更适用于加固较深、较厚的软粘土、淤泥质土地基,特别对超软粘土加固效果更为显著。其优点是施工过程中无振动、无噪音,对环境无污染,对土体无侧向挤压,对邻近建筑物影响很小,且工程造价低廉,施工速度快。因此,在一般多层房屋建筑和中小型水工构造物的软土地基加固处理工程中被广泛采用。同时也可用作基坑开挖的边坡支护结构和处理边坡失稳等工程。
There are many ways to reinforce and treat soft soil foundation at home and abroad, such as replacement method, dynamic compaction method, cement mixing pile, compaction grouting, silicified ground and gravel pile. In terms of its scope of application, cement mixing piles are more suitable for reinforcing deeper and thicker soft clay, silty soil foundation, especially for super soft clay reinforcement effect is more pronounced. Its advantage is no vibration during construction, no noise, no pollution to the environment, no lateral extrusion on the soil, little impact on the adjacent buildings, and the project cost is low, the construction speed is fast. Therefore, in general multi-storey buildings and small and medium-sized hydraulic structures in the soft soil reinforcement project has been widely used. At the same time, it can also be used as slope supporting structure for excavation of foundation pit and for dealing with instability of slope.
