摘要
通过对某核电护岸进行原位测试,分析地面沉降机理,利用岩土工程和数学模型法,预测该区域未来的沉降情况。结果表明,主要沉降集中在填石下部土层,上部填石层沉降量较小,为整体沉降。从2020年8月起,两种方法预计的总沉降量分别为598.5~926.0 mm、246.4~760.4 mm,沉降时间为32.1~60.2 a、22.7~41.9 a。
Through in-situ test of a nuclear power revetment,the mechanism of land subsidence is analyzed,and the future settlement of the region is predicted by geotechnical engineering and mathematical model method.The results show that the main settlement is concentrated in the lower soil layer of rock fill,and the settlement of the upper rock fill is small,which is the overall settlement.From August 2020,the total settlement predicted by the two methods are 598.5 mm to 926.0 mm and 246.4mm to 760.4 mm,respectively,and the settlement time is 32.1years to 60.2 years and 22.7years to 41.9 years.
