摘　　要：为合理设计楼庄子水库填筑料,现场料场勘查及室内试验结果表明:黏土心墙坝心墙土料选择T1、T2土料场,压实度采用P≥0.99,土料设计干密度为1.81 g/cm^3,填筑含水量为11.37%~16.75%;3个砂砾料场均可满足坝壳填筑要求,其相对密度均采用0.85,砂砾料的设计干密度分别为2.16 g/cm^3和2.18 g/cm^3。实际施工过程中,心墙黏土料、坝壳砂砾料实际平均干密度均大于设计干密度,实际压实标准满足设计要求。设计和实际施工结果可为同类工程提供参考。In order to rationally design the filling materials of Louzhuangzi Reservoir,the site survey and indoor test results show that core wall soil for the clay core dam is selected from T1 and T2 borrow,the compaction degree is P≥0.99,and the design dry density is 1.81 g/cm^3,the embankment water content is 11.37%to 16.75%;the three gravel quarries can meet the dam shell embankment requirements,and the relative density is 0.85.The design dry density of the gravel is 2.16 g/cm^3 and 2.18 g/cm^3.In the practical construction process,the dry density of the clay and gravel of the core wall is higher than the design dry density,and the actual compaction meets the design requirement.The design and the actual construction results can provide reference for similar projects.
