| 中文摘要: |
| 某土石坝坝轴线长达1172 m，在如此长的大坝地基范围内，分布有上第三系20多个地层，地层与地层之间的力学指标差异较大，地质条件十分复杂。如何解决坝体的不均匀沉降，是该拦河坝工程的关键技术问题。为解决这一技术难题，本文采用理论计算和离心模型试验相结合的方法，论证了采用分期、分段预压的设计和施工筑坝技术的可行性，水库建成3年后坝体沉降观测值3 cm事实，验证了该设计和施工方案的正确性。 |

| The length of an earth-rock dam is up to 1 172 m, of which more than 20 strata make the mechanical in-dex of those layers different.For such complex geological conditions, how to solve the problem of uneven settlement of the dam is the key to the project.In order to solve the technical problems, this paper proves the feasibility of pre-compaction in different periods and sections.The reservoir has been running for three years, and the fact that the observed value of the dam settlement is 3 cm, verifies the correctness of this design and program. |
