大坝填筑施工前必须对填筑料进行现场碾压试验以确定合理的碾压参数，并对设计控制标准进行复核。通过开展猴子岩面板堆石坝现场生产性碾压、载荷及直剪试验，得到了堆石料干密度、孔隙率、渗透系数、变形模量等参数的准确结果。分析表明，色龙沟料场灰岩堆石料的抗滑稳定性、抗承载及抗变形能力较好，设计填筑压实标准合理。
大壩填築施工前必鬚對填築料進行現場碾壓試驗以確定閤理的碾壓參數，併對設計控製標準進行複覈。通過開展猴子巖麵闆堆石壩現場生產性碾壓、載荷及直剪試驗，得到瞭堆石料榦密度、孔隙率、滲透繫數、變形模量等參數的準確結果。分析錶明，色龍溝料場灰巖堆石料的抗滑穩定性、抗承載及抗變形能力較好，設計填築壓實標準閤理。

Before filling construction of a CFRD, in-situ rolling tests should be carried out to determine reasonable rolling pa-rameters, also through which the design control standard can be rechecked. By conducting rolling and loading test as well as di-rect shear field test of CFRD at Houziyan Hydropower Station, accurate results of dry density, porosity, permeability coefficient and elastic modulus were obtained. The analysis results show that anti-sliding stability, loading capacity and anti-distortion capacity of limestone material in Selonggou material field is good, the designed filling compaction standard is reasonable.
