According to the data of field observations, the behaviours of defor- mations and stresses in Hengshan earth dam are studied in this paper. It has been proved that settlements and displacements may be expressed by hy- perbolic equation. Displacement ratio is almost independent of time. 2-4 Years after completion of the dam, settlements are nearly stable. The ratio of stable settlements to ultimate settlements is over 80%. When the reservoir is first impounded there is obvious influence on settlements at upstream crust of dam. Settlements on different levels in the clay core are also studied. After construction, the pore water pressure obviously increases and the earth pressure decreases in the clay core. These phenomena are un- usual. 本文通过原体观测资料的分析研究了横山土坝的变形及应力特性。分析表明,横山坝的沉降和位移均可用双曲线方程表示,位移比基本上不随时间而变,可视为常数。坝竣工2-4年后,变形即基本稳定。此时,稳定沉降达最终沉降的80％以上。水库首次蓄水对上游坝壳的沉降有较大的影响。另外,也研究了心墙分层沉降的特性。心墙内的孔除水压力有明显增大,而土压力则减小,这些现象是不正常的。 << 更多相关文摘 相关查询
