强夯时的夯击能量,一般都集中在夯点上,而夯点布置则视土质情况和加同深度而定。在通常情况下,为查明夯击效果,往往要在夯击过程中进行大量观测工作,比如:沉降观测、压力观测、孔隙水观测以及振动观测等。据计算,这些观测项目所需费用约占整个工程费用的一半。 Dynamic compaction when the ram energy, are generally concentrated in the ram point, while the ram arrangement is based on soil conditions and Canada with the depth may be. Under normal circumstances, in order to find out the impact of tamping, it is often necessary to carry out a large number of observations during tamping, such as settlement observation, pressure observation, pore water observation and vibration observation. It is calculated that the cost of these observations accounts for about half of the total project costs.
