| 摘 要： | 广西郁江老口航运枢纽工程泄水闸坝坝基岩石具有岩性较软,抗压强度低,软弱夹层较发育,泡水膨胀、失水易开裂等特点。坝基泥岩类岩石存在承载力偏低、快速风化、抗滑稳定、软硬夹层对基础变形的影响等工程地质问题。通过大量的勘探、试验手段,基本查明了泄水闸坝坝基岩体的特性、规律,为水工设计解决这些工程地质问题提供了较为准确、科学的地质参数及处理建议。

| Abstract: | The rock of sluice dam foundation of Yujiang Laokou shipping hub project of Guangxi has the features of soft, low compression strength,developed weak interlayer,and expansion and crack.The mudstone rock will influence the project quality,for such rock is too soft to bear heavy weight,weathered quickly,unstable.Through lots of prospect,experiments, the paper mainly studies the features of the rock and some rules and offers precise and scientific geological parameter and useful solutions to geological problems. |
