通过数值模拟、室内动光弹试验、仪器设备组合改进与研制及现场试验,对混凝土截渗墙质量无损检测声波相控技术进行了较为深入的研究。
According to the characters of the reservoir impoundment,geology and structures of a plain reservoir,a cutoff wall model is built,and three dimensional finite element method is used to simulate the dynamic variation process of the reservoir water in the foundation near the dam site.
根据某平原水库的蓄水过程和地质、结构特点,建立了包含截渗墙在内的水库大坝计算模型,采用三维有限元方法模拟了水库蓄水位不断变化时,坝基截渗墙的应力变形状态。

Influence of reinforcement of cut-off walls for dikes on groundwater quality of polder areas;
堤防截渗墙加固对圩区地下水水质的影响
In order to lower the phreatic line and avoid instability caused by seepage, the vertical cut-off wall is built in some river embankments.
许多堤防工程为了防止渗流破坏及降低浸润线,修建了截渗墙,但截渗墙的修建对堤坡的稳定性到底有什么影响,需要进行分析和论证。
The cutoff collars of the conduit were too close to each other and too large in diameter.
破坏原因是新建泄洪涵洞处原土坝开挖断面狭窄,左侧边坡偏陡,涵洞外壁截渗环过密,环径大,新填坝体填筑速度快,上部质量低,完工后立即蓄水,新填土坝左侧不均匀沉降过大,坝顶出现横向裂缝,当库水位接近正常蓄水位时,渗流从下游坝坡较高处逸出,出口无反滤保护,坝顶裂缝渗流冲刷,导致溃坝。
