Changing patterns of soil parameters considering...
Along the direction of the row pile,there are 9 monitor points surrounding the piles,which is shown in Figure 5.Regarding complete construction of each single pile as a construction condition,which is,a total of 60 conditions.An analysis on changing patterns of the influence of 60 construction conditions on the soil around the pile is conducted.
As Figure 6 shows,since the construction process such as drilling and pile formation will produce disturbance to the soil around the pile,seven monitor points C to H will have sudden changes in soil settlement at the beginning of the construction of the nearest pile.Settlement value maintains high grow th rate in 1 0 following construction conditions with a maximum of 66%.Among all the monitor points,the settlement points of the monitor points E and F at the section of the cross-section Y=60 m and Y=70 m are the largest,which is correspond with the settlement distribution law at the end of construction mentioned before.That is,considering construction process,a large settlement also occur at the 2/3 length of the isolation pile construction direction.So more attention should be paid to the monitoring and protection of structure surrounding piles during the construction process.
