通过甲基纤维素与六甲基二硅亚胺的反应，成功地实现了对水溶性物质甲基纤维素醚三甲基硅化的改性；红外光谱验证了反应的发生，核磁共振氢谱确定了三甲基硅甲基纤维素的取代度；纤维素醚上的部分羟基被三甲基硅化后取得了在普通溶剂中的良好的溶解性，且随着取代度的增加，在非极性溶剂中的溶解性逐渐变好；通过热失重实验，对其热稳定性进行了测试。

It is concluded that because the mica schist is mixed with feeble weathered granite, the grain is broken up severely; the back-analysis parameters of explosion rockfill(3BⅠ)are lower than the results of laboratory triaxial test, and the Duncan E-B parameters obtained by back-analysis of her sandy gravel (3BⅡ)are higher than the triaxial test results of laboratory triaxial test which can not reflect the mechanical behaviors of the dam material objectively; the research should be strengthened in 300 m high rockfill dam construction. The fitting modes of the space displacement field of prototype observation are also explored and it turns out that the results of IGA analysis considering only vertical deformation meet the need of dam's technical accuracy.

结果表明，由于在微弱风化花岗岩掺加云母片岩，颗粒破碎严重，爆破堆石料（3BⅠ）的原级配粗粒料反演参数远低于室内三轴试验成果；与3BⅠ堆石料相反，砂砾料（3BⅡ）现场反演得到的邓肯E~B模型参数高于室内三轴试验值；室内三轴试验成果不能客观反映筑坝材料的力学特性，对于当今的300 m级高土石坝建设，宜加强对原级配粗粒料的力学特性研究；同时对原型实测的空间位移场不同拟合方式进行了探讨，认为仅考虑铅直向变形的IGA参数反演成果能基本满足土石坝工程的精度要求。

The change of REE composition between the upper and lower samples from Hongcan well implied the tectonic setting and property of the sediment provenance in Zoige Basin were altered obviously between late-period of Middle Triassic and mid-period or late-period of Late Triassic. This change was probably due to elevation and erosion of the matured continental crust on the east of Zoige Basin, and lots of clastic materials transported into the basin in late-period of Late Triassic.

通过对比杂砂岩稀土元素组成在上层和下层样品之间的变化，若尔盖盆地内中三叠世中期到晚三叠世中期及晚期沉积物源区的构造背景和性质发生了明显的改变，而这一变化很可能是盆地东侧成熟陆壳在晚三叠世后期被抬升和剥蚀，其大量碎屑物质被带到盆地的结果。
