航道养护工程中浅层软土地基处理方案

结合通吕运河通州大桥—通灵大桥段右岸航道护岸养护工程,对短木桩和块石换填地基处理方案的承载力和沉降量及工程费用进行了计算分析,通过比较分析,短木桩复合地基处理方案具有提高地基承载力和减少地基沉降的功效,且费用较低,是浅层软土地基处理的有效方法。

Shallow soft soil treatment scheme in waterway maintenance engineering

Combining with the maintenance engineering work on the right side of bank-protection of Tonglu Canal from Tongzhou bridge to Tongling bridge,this paper calculated the bearing capacity,the settlement amount and engineering cost by the treatment scheme of timber-pile and block-stone-filling foundation respectively.The comparison and analysis results show that the timber-pile foundation composite foundation scheme will result in greater the bearing capacity,less settlement and lower cost,thus it is an effective method for shallow soft soil treatment.
