石灰稳定膨胀土的效用及其施工质量控制

Effectiveness of stabilized expansive lime soil and construction quality control

膨胀土的胀缩性可引起地基的变形,甚至危及构筑物的安全。对于膨胀土路段,路基的稳定是工程建设成功的关键。在论述石灰稳定土加固机理的基础上,结合工程实例,论述了膨胀土路段石灰稳定的施工要点及石灰稳定膨胀土路段的施工质量控制。

The swelling of the expansive soil when wetted and shrinkage when dried may cause the deformation of subgrade and even endanger the security of building.Therefore,for road sections of expansive soil the stability of the roadbed is the key to the success of a project.On the basis of the consolidation mechanism of the lime stabilized soil and a practical example were discussed the construction mainpoints for stability of the road section of the expansive lime soil,as well as the construction quality control of the road section.
