摘要
通过一系列无侧限抗压强度试验,研究了不同含盐量下土料Ip对二八灰土强度的影响规律,结果表明,试样强度随着土料Ip值的增大而增大,且呈先慢后快的增大趋势,试样强度随着含盐量的增大而减小,土体Ip越大,土体强度受含盐量影响也越大。
Through a series of unconfined compressive strength tests,the effect rule of soil Ipon 2∶ 8 lime-loess strength in different salt contents was studied. The test results show that the 2∶ 8 lime-loess strength increases with the increase of soil Ip,and the growth appears first quick back slow trend,the 2∶ 8 lime-loess strength decreases with the increase of salt content,the strength of soil with larger Ipis more sensitive to salt content.
