摘要
新疆开都河博湖县城区段应急防洪工程主要分布有第四系粉砂、细砂、中砂等易发生地震液化的土层,有的已产生破坏,对拟建的堤防具有较大的潜在威胁,影响堤防的正常生产运行。通过查明液化土层的分布、深度、液化等级,对堤防地基土的液化土层进行抗液化处理,避免地基土不均匀沉陷和开裂对堤防地基造成破坏,以期从根本上解决堤防地基的液化破坏,保证堤防的正常运行。
Flood control emergency project of Kaidu River in Bohu county is mainly distributed quaternary silt,fine sand, medium sand, and some have been damaged. It has a great potential threat to the proposed embankment, whieh affects the normal production and operation of the embankment. This paper attempts by identifying distribution, depth and liquefaction grade of liquified soil, avoid soil foundation uneven settlement and cracking damage of levee foundation, fundamentally solve the levee foundation liquefaction failure, ensure normal operation of embankment.
