高等级公路稳定砂土底基层研究

Study of Base Stabilized Sandsoil under the Expressway

唐港高速公路沿线大多路段为粉质低液限砂土及粉砂，只有少量路段为低液限粘土，为了提出该地区合理的砂基层加固方案，结合唐山地区自然地理条件、沿线土质分布状况以及稳定类材料供应情况进行了砂基层加固科学试验研究，并对稳定土的强度形成机理及影响因素进行了探讨。

Along the line of Tang Harbour Expressway in province Hebei there are bearing silt sandsiol of low liquid limit and siltsand in great mojority sections, only in few sections there are bearing soil. To find out the rational method of stabilizing sandbase in this region the scientific experiments are made in Lab combined with geographical、soil distribution and material with stabilized soil in Tangshan region. The mechanism of strength formed and factor of influence on strength are explored.
