It analyzes the reinforcement mechanics of lime pile in the building from three aspects of earth among pile,pile body,compound foundation,and introduces the lime pile design method and project test method,which shows the lime pile used is suited to reinforce the foundation treatment in the existing buildings.
从桩间土、桩身、复合地基三方面分析了石灰桩在建筑物中的加固机理,结合工程实例,介绍了石灰桩的设计方法及工程质量检验方法,证明了采用石灰桩进行既有建筑地基加固处理是可行的。
Normally,the ram-compaction pile body is bored concrete pile,whose quality can\'t be guaranteed in deep and thick soft ground.
复合载体桩桩身常用混凝土灌注桩,在深厚软土地区其桩身质量不易保证;采用PHC预应力管桩作复合载体桩桩身,既可提高其桩身承载力,又易于保证桩身质量。
Lead on to the defect in pile body of bored caisson pile, mainly relate to wall mud, boring drill rate, 3 materials of concrete (cement, sand,stone), water cement ratio and mixing quality controlled by concrete under water when pouring, self defect of pouring conduit, and operation way heighten conduit, and so forth.
导致钻孔灌注桩桩身缺陷,主要与护壁泥浆、成孔钻速、组成砼的三大材料(水泥、砂、石子)、在灌注时水下砼控制的水灰比及搅拌质量、灌注导管的自身缺陷、以及提升导管的操作方式等有关,根据一些工程实例,分析了形成桩身缺陷的具体原因,并提出了防范措施。
The test data show that the axial force of pile at any posi.
随着填土荷载的增大,不同深度处桩身轴力均呈现增大的趋势,但增加幅度不同,桩身轴力最大点位置随填土荷载增大变化很小,路基进入预压期后桩身轴力仍逐渐增大,但变化幅度逐渐减小。
The inspection methods and evaluation standards of pile shaft quality in common use are briefly introduced.
简述了桩身质量检测的常用方法及评判标准,采用主成分分析原理与关联度分析原理,结合搅拌桩检测资料,对影响桩身质量的因素进行了分析研究,得出了一些有价值的结论,对搅拌桩检测方法及评判标准的改进与完善具有参考意义。
