excavation and dewatering works for the 3 tall buildings in Xinhejiayuan Community are introduced. In the projects

the composite subsoil of piles with rammed and enlarged base forms a similar mat foundation under box foundation; and by the effect of jostle dissolves stratum liquefaction the piles don’t drill through so as to shorten piles greatly and lower greatly the soil treatment cost. Not only the blank of geotechnical investigation & design for tall buildings in Renqiu District has been filled up by the projects

but it is also pointed out that piles with rammed and enlarged base are important to tap the potentialities of shallow liquefiable stratum.
