摘要: |
针对上海地区湿软粘土的路基条件和多雨的气候特征,提出采用水泥-石灰综合处治路基的技术措施,并对水泥-石灰土的路用性能进行了室内试验与现场测试研究,结果表明,与石灰土相比,水泥-石灰土的早期强度和模量较高,后期强度和模量增长缓慢,增幅也较小;水泥-石灰土的强度与模量均能充分满足高等级道面的设计要求,且受含水量的影响较小,因此,采用水泥-石灰土对于雨季施工和缩短工期具有重要意义。 |

Abstract: |
In accordance with the road subgrade condition and the climatic characteristics in Shanghai area, cement lime soil stabilization was proposed to strengthen the subgrade soil. In this paper, the performance of cement lime stabilized soil was studied by means of experimental road tests. It is shown that strength, modulus and water stability of cement lime stabilized soil may fully meet the needs of high grade pavements. |
