陕西省第二建筑设计院在1973年设计的某工程,地基为杂填土,系参考原西安市杂填土地基研究小组的“灰土加密桩基础”一文,采用了灰土挤密桩处理杂填土地基,效果较好,地基承载力提高了近一倍,工期30天,仅为一般地基处理工期的1/2～1/3。现场施工人数最多时为30人,后期采用了机械夯实,大大减轻了工人的劳动强度。同时还 A project designed by the Second Architectural Design Institute of Shaanxi Province in 1973, the foundation of which was miscellaneous filling, referenced to the original “Xin Soil Encryption Pile Foundation” article of the Xi’an Miscellaneous Filled Soil Subgrade Research Group, using lime soil compaction piles Miscellaneous filling of the ground, the effect is good, the bearing capacity of the foundation has increased nearly twice, the construction period is 30 days, only 1/2 to 1/3 of the general foundation treatment period. The maximum number of on-site construction workers was 30. The later use of mechanical compaction greatly reduced the labor intensity of workers. Also
