Construction method for roadbed of spoil ground
The invention discloses a spoil ground subgrade construction method, which comprises the following steps: for a road section with the spoil (slag) thickness not greater than a preset thickness of a spoil ground, firstly excavating, then backfilling and rolling in a layered manner, mingled bad soil waste (not used as filler) such as household garbage, and for a section with the spoil (slag) thickness greater than the preset thickness, firstly excavating a spoil layer at the upper part of the superficial surface, and then backfilling and rolling in a layered manner; and after the abandoned soil layer is excavated and the foundation layer is exposed, a dynamically-compacted gravel pier group is adopted for replacement. According to the invention, the problem that the highway passing through the spoil site is easy to generate large settlement and non-uniform settlement in the road section within the range of the spoil site is solved.
本发明公开了一种弃土场路基施工方法，通过，对于弃土场的弃土(渣)厚度不大于预设厚度的路段，采用先开挖后分层回填碾压，夹杂的生活垃圾等不良土废弃(不用作填料)，而对于弃土(渣)厚度大于预设厚度段采用浅表上部先开挖弃土层，开挖弃土层之后露出地基层后采用强夯的碎石墩群置换。本发明解决了穿越弃土场的高速公路，在弃土场范围内的路段容易产生大的沉降和不均匀沉降的问题。
