| 中文摘要: |
| 由于桩帽的存在，PTC桩复合地基的变形规律与一般的复合地基的变形规律存在一定的差异．为了解带帽PTC桩复合地基的作用机理，掌握其沉降变形、承载特性、荷载传递、桩土应力比及桩土间相互作用规律，进行了带帽PTC桩复合地基现场足尺试验研究，得到了一系列有益的结论，将对其设计优化起一定的指导作用。 |
| 英文摘要: |
| The deformation law of this composite foundation is different from the common style because of the cap on the pile top.In order to investigate working mechanism,and master the mechanical behavior of the settlement deformation,loadbearing capacity, load transfer, pile-soil stress ratio, pile-soil interaction of control settlement the test about sparse piles composite foundation with PTC under high fill embankment is carried out.There are some useful results by the experiment. The test results can provide useful information for the engineer to study the theory of control settlement and sparse piles composite foundation with PTC, and guide design control settlement and sparse piles Composite Foundation with PTC under flexible foundation. |
