粉喷搅拌桩、白灰桩、碎石桩在天津市停止使用之后,对于民用建筑、中小型工业建筑中的基础工程,能够取代它们的则是夯扩桩。现以龙滨园小区为例,说明夯扩桩的应用。 1 场地及地质概况 龙滨园小区位于水上公园南侧,原为大而深的水坑,后来的填垫物杂乱。地形呈南高北低趋势。 根据地质勘察,在场地埋深35m左右的范围内,最上层是人工填土层,一般厚度5.5～8.5 m, After powder jet mixing piles, white ash piles, and gravel piles were discontinued in Tianjin, for civil engineering and infrastructure projects in small and medium-sized industrial buildings, ramming piles could replace them. Take Longbinyuan Residential Area as an example to illustrate the application of ramming piles. 1 Site and Geological Overview Longbinyuan Community is located on the south side of the water park and was originally a large and deep puddle. Later padding was disorderly. The terrain is low in the south and high in the north. According to geological survey, in the range of about 35m depth of the site, the uppermost layer is an artificial fill layer, and the general thickness is 5.5-8.5m.
