The paper proves the advantage of evaluating sand filling compactness by reinforcement penetration method and makes the contrast test of reinforcement penetration and ring sampler method so as to discover the method for determining the relation between dry density and reinforcement penetration of sand filling.
论证了采用钢筋贯入法评定填砂密实度的优点;对钢筋贯入度和环刀法进行对比试验,找到了确定填砂的干密度和钢筋贯入度之间关系的方法,使采用钢筋贯入度试验检测砂的密实度时,评定结果更为科学。
Adopting sand filling embankment in areas rich in coarse sand and medium sand can save a lot of arable land,reduce machine-team greatly,at the same time,the technical indexes of embankment can meet the specifications,and the construction period is also less affected by wet weather,so it is of great practicability.
