关于深基础施工中的抗浮问题

ANTI-FLOATING PROBLEMS DURING CONSTRUCTION OF DEEP FOUNDATION WORK

高水位地区深基础施工中由于停电、排水系统故障、总体降水能力不足等原因，会在雨季施工中造成基础上浮，处理费用高。可通过抗浮稳定计算并采取包括注水等稳定措施解决。

During construction of deep foundation work in underground of high water level region,there are often some accidental events occured in raing season construction such as shortage of electricity, accident of drainage system,and insufficiency of dewatering capacity etc,and eventually, that would cause the floating of its deep foundation.Of course, its antifloating treatment would be very costly. This could be avoided if stability measures including anti-floating calculation and anti-floating watering method were duly adopted.
