摘要： 变形模量是岩土工程力学特性的一个重要指标，现场压板荷载试验计算变形模量是最直接有效的方法。河北张河湾抽水蓄能电站上水库边坡施工开挖后全强风化细砂岩出露较多，对沥青混凝土面板的变形影响较大，通过对不同风化程度的细砂岩取样进行细砂岩变形模量试验，为工程设计提供地质依据。

Abstract: Deformation modulus is an important parameter of the geotechnical materials. The in--situ plate loading test is a direct as well as effective method measuring the deformation modulus. The sandstone rock mass was exposed after the upper reservoir slope excavation for the Zhanghewan PumpedStorage Power Station. The exposed sandstone rock mass might have an adverse impact on the deformation of slope with asphalt concrete facing. Extensive in--situ plate loading tests were performed on the sandstone bedrock with various degrees of weathering.

Key words: Deformation Modulus, Stabilized Settlement, In--Situ Testings
