For High Rockfill Embankment Construction Settlement Observation And Quality Control Method

With the rapid development of high class highway In China,rock asembankment biling material will be used very widely,especially In the westernarea。therefore the study on quality control methods for rock filling and discussiononthe settlementrulesofhlghrockembankmentwllIbethekeyproblems Intheconstruction of high class highway In our country． First,the existing achievements In highway and dam constructionengineering are summarized and the compactlon properties of rock Is discussed Inthis paper．Then the methods for determining compactlon techniques andcontrolling compactlon quality are put forward In RENZAI second class highwayIn GuangXI Zhuang autonomous region．This study also designed settlementobservation Program In tyPical section,so settlement datas not only of roadbedbut also of rock till embankment can be abtalned both during construction periodand after hnlshed time,which can be used not only to monitor the stability ofroadbed but also provide further rock embankment settlement analysis withreliable data support．Besides。based on discussion of the existing settlementcalculation method Is brought forward In light of Dencan－Chang nonlinear elasticmodel Inthls paper．A practical computerprogram Is worked out and muchsettlement calculating was carried out by this program The results show that thetheoretical values agreed well with those practical ones．After analyzing the rockhll embankment settlement data with probability method。a conclusion can bemade or deduced that the embankment compacted by the method In this paper hasreached elastic state and can meet various kinds of dynamics demand as roadbed．...
