摘要
螺杆桩技术的诞生，开创了变截面桩的新思路。本文扼要介绍了螺杆桩的构造、受力原理及工法，并创建了与之结果相匹配的计算公式和相关的计算参数等。通过对实际工程的运用，取得了静载试验与计算结果的对比资料。并对公式的合理性、可行性进行了验证。
The screw stake is a new technology and a new concept of section-changed stake. This text introduces the structure of the screw stake and the principle of force suffered and the working methods in summary, and establishes the calculation formula and related calculation parameters etc. Compare the calculation results to the experimental results obtained from the actual usage of the engineering. And carry on the verification to the rationality and feasibility of the formula.
