摘要
处于软土地带的输电线路,多应用灌注桩。灌注桩设计时要注意桩基、桩径,桩持力层的选择,承台桩以及钢筋配置要求等,要根据实际情况充分考虑。灌注桩的施工工艺复杂,而且对灌注桩的质量有非常大的影响,所以要严格控制浇注过程,对施工过程要加强管理。灌注桩工程既要做到能满足使用要求,又要能最有效地利用和发挥地基土和桩身材料的承载性能,在设计、施工、管理及难点处理中,要全面考虑各方面因素,严格保证工程的质量。
Cast-ln-place piles are preferred for transmission lines in regions with soft soil. In the pile design, the requirements for selection of pile foundation, pile size, and bearing stratum, as well as supporting pile and reinforced steel bar configurations, etc, should be fully considered based on actual situation. The process of cast-in -place pile is very complicated and has significant impact on pile quality. Thus both casting process and construction process must be controlled rigorously. The construction must not only meet use requirements, but also make full use of the bearing capabilities of foundatlon soil and pile material. Therefore, during design, construction, managing and problem solving processes, all the factors have to be taken into account, and construction quality must be ensured.
