1长江口导堤在波浪荷载作用下的稳定性研究显示文摘长江口导堤在建造期间遭到了强风暴的袭击,致使一部分沉箱结构沉入土中1~5m,或偏移初始位置20m。通过动三轴试验模拟波浪荷载作用下地基的变化情况,试验结果显示,沉箱的过度沉陷和侧移是由于强风暴使得软黏土强度弱化所致。根据试验结果,提出排水板加堆载预压的方法来加固软土地基,并证明该方法的有效性。在加固的软土地基上对导堤进行重建,重建后经历几次强风暴该导堤无损坏迹象。闫澍旺 侯晋芳 刘润 范期锦 谢世楞 2006岩石力学与工程学报2006,25,z1:11
2Stability of the Guiding Dike in Yangtze Estuary Under the Wave Load显示文摘During the construction of the guiding dike in the Yangtze Estuary, some of the caisson structures sank into the soil for 1~5 m or slid about 20 m away from the original place when a strong storm attacked this area. Dynamic triaxial tests were carried out to simulate the behavior of foundation soils under wave loading. The test results show that the excessive settlement and lateral movement of the caissons are due to the weakening of the soft clay strength during the strong storm. The test results also show that the ability of the soft clay to resist the wave force will be greatly increased when the soft soil samples are suitably improved. Based on the test results, an improvement method combining vertical drains with surcharge loading was proposed to strengthen the foundation soil. On the improved soil foundation, the dike has been reconstructed and undergone several strong storms without any damage. A finite element approach has been developed for analyzing the settlement and stability of the dike under the action of strong storm.闫澍旺 刘润 范期锦 谢世楞 2005China Ocean Engineering2005,19,4:6
3波浪荷载作用下防波堤地基软化特性的试验研究显示文摘长江口防波堤在建造期间遭到了强热带风暴的袭击,致使一部分沉箱结构或沉入土中1~5m,或偏移初始位置20m。本文通过动三轴试验模拟了波浪荷栽作用下地基的变化情况,试验结果显示,沉箱的过度沉陷和侧移是由于强风暴使得软粘土强度弱化所引起的。根据试验结果,提出了竖向排水联合堆栽预压的方法来加固软土地基,为证明该方法的有效性,在加固的软土地基上对防波堤进行了重建。重建后经历几次强风暴该防波堤无损坏迹象。闫澍旺 杨昌民 范期锦 谢世楞 2006港工技术2006,43,2:3
