摘要

为减小高液限土弃方处理或改良填筑造成的经济损失

通过室内试验研究了高液限土的基本特性

并结合现场路填筑试验

研究了其直接填筑性能和相应的质量控制参数。研究结果表明:高液限粘土和含砂高液限粘土可用于路堤直接填筑

填筑质量宜通过含水率、压实度、空气率3个参数控制;填筑过程中含水率应满足-2%≤ω-ωop≤6%;填筑碾压后的压实度应大于90%;高液限粘土空气率控制范围为4%≤va≤8%

含砂高液限粘土空气率控制范围为va≤13%。

Abstract

In order to reduce the cost of discarding or improving high liquid limit soil

the fundamental characteristics of high liquid limit soil are studied through the indoor tests

and the construction properties and quality control parameters are researched based on field reclamation test.It is shown that high liquid limit clay and sand-carrying high liquid limit clay can be used directly as embankment filling.The construction quality can be assured by controlling the parameters of water content

degree of compaction

and air rate.The basic required water content for construction should satisfy the equation of-2%≤w-wop≤6% and the degree of compaction should be greater than 90%.The air rate of high liquid limit clay should be in the range of 4% to 8% while the air rate of sand-carrying high liquid limit clay should be no more than 13%.
