| 摘 要： | 拟建的枯河渡槽及退水闸建于黄河冲积平原上，通过地质勘探查明了渡槽及退水闸基础的岩性特征、工程地质条件及各持力层土体的物理力学性质．勘察结果表明，工程场区地层主要由第四系冲积及坡洪积黄土状壤土和粉质粘士组成，地层分布稳定、厚度大于32m，总体来看，场区工程地质条件较好，但第四系上部黄土状土具有湿陷性，强度略低．为此，针对建筑物的性质提出了供设计和施工使用的物理力学性质建议值。

| Abstract: | The aqueduct across Kuhe River and escape sluice to be built are located on the Yellow River alluvial plain. The geologic investigations have revealed the foundation characteristics, geological conditions and physico-mechanical properties for the supporting course of soil. The site area mainly consists of Quaternary deposits, talus-diluvial loess-loamy material and silty clay layer. The formations are steadily distributed with a total thickness of more than 32 m. In general, the site engineering geology conditions are favourable, but the Quaternary deposits have at higher portion a significant wetting collapse and lower resistance. For this reason, some special values of physico-mechanical indexes for designing and constructing related structures are recommended. |
