| 摘 要： | 沉管灌注桩施工中桩径的控制是保证其质量的重要因素.通过对沉管内砼体的受力分析,并用2个工程实例,探讨了管内砼柱面的相对高度在一定的条件下对充盈系数的影响,认为不仅提管时间和机械原因能影响灌注桩桩径(即充盈系数)的大小,而且选用不同的加灰频率、严格控制管内砼柱面的相对高度,也明显地影响充盈系数的大小,其对保证灌注桩的施工质量,提高经济效益具有重要的意义.

| Abstract: | The controlling of bored piles diameters is a very important factor influencing construction quality. Take two projects for example, the relative height of the concrete influencing the flooded index is researched through the stress analysis of the concrete in the pipes. The results show that not only the time of pullimg out pipes and mechanical reasons, but also the frequency of pouring cement and controlling the relative height of the concrete in the pipes obviously influence the flooded index . It is propitious to ensure the quality of the construction and increasing economic effects. |
