在黄土中掺入不同比例的石灰进行改良,并对改良土进行大量的土工试验和理论分析。研究表明:在黄土中掺入石灰可使含水率的控制范围变宽;石灰的掺入能有效的降低黄土的压缩性;相比重塑黄土,石灰改良土具有更好的强度特性和水稳定性,可以较好地满足高标准铁路建设需要。
In the loess mixed with different proportions of lime for improvement, and a lot of soil improvement test and theoretical analysis. The results show that limestone is blended into the loess to broaden the control range of water content. Lime incorporation can effectively reduce the compressibility of the loess. Compared with the remolded loess, lime modified soil has better strength characteristics and water stability It can better meet the needs of high standard railway construction.
