泥炭类土在我省长白山区的低湿地带分布很广,在其上通过的公路,极易产生路堤失稳和工后沉降过大的问题,从而造成路基变形和破坏。本着就地取材的原则,根据泥炭层厚度的不同,利用沿线的砂砾和山皮石这两种优良的粒料对其进行改善和处理,可以达到使用要求的效果。 Peat soil is widely distributed in the low-wet zone of Changbai Mountain area in our province. The roads passing above it are prone to cause instability of embankments and excessive settlement after construction, resulting in the deformation and destruction of roadbed. In line with the principle of local materials, according to the different thickness of peat layer, the use of grit along the line and the two good Shanpi stone to improve their handling and processing, can achieve the desired effect.
