摘要
河岸侵蚀是塔里木河沿岸面临的主要自然灾害之一。随着土工织物材料在建筑行业的日益普及,土工织物袋、土工织物管在河岸保护工程广泛应用。现有的研究对这些工程施工后性能的研究很少。本文介绍了一项护岸工程施工后性能的研究结果,通过采用简化钻孔方法,以及详细的实验室试验结果和分析确定了岸边土的性质。本文还研究了护岸工程实施后,河岸附近河流流态的变化及由此产生的淤积情况。为了预测护岸工程竣工后第一年内因淤积而导致的砂坝形成情况,对淤积区进行了勘测,并绘制了等高线。根据淤积区的等高线确定了最终的水流模式。对护岸工程竣工后3年期间的卫星图像进行分析,以此得出护岸工程的防护效果。
River bank erosion is one of the major natural disasters along the Tarim River basin.With the increasing popularity of geotextile materials in the construction industry,geotextile bags and geotextile tubes are widely used in river bank protection projects.There are few researches on the performance of these projects after construction.This paper introduces the research results of the performance of a bank protection project after construction,and determines the properties of the bank soil by adopting simplified drilling method and detailed laboratory test results and analysis.This paper also studies the change of river flow pattern and the siltation caused by it after the implementation of the bank protection project.In order to predict the formation of sand dams caused by siltation in the first year after the completion of the revetment project,the siltation area was surveyed and the contour lines were drawn.The final flow pattern is determined according to the contour line of the silting area.This paper analyzes the satellite images in the three years after the completion of the bank protection project,and obtains the protection effect of the bank protection project.
