从海平面造成的影响预测下辽河平原区未来的砂土液化灾害

Impacts of Sea level Rise on Sand Soil Liquefaction in Xialiaohe River Plain

未来的海平面上升将对沿海地区的经济发展和自然环境造成重大影响。下辽河平原区是辽宁沿海经济带的组成部分,也是容易产生砂土液化灾害的地区。从讨论砂土液化灾害致灾因素着手,分析了该区未来的地震趋势和因海平面上升带来的地下水水位变化,预测下辽河平原区未来百年可能产生一次或多次局部较严重的砂土液化灾害,而产生大面积砂土液化的可能性不大。

Sea level rise significantly impact economic development and environment. Liaoning Xialiaohe River Plain is part of coastal economic zone and is prone to produce sand soil liquefaction hazards. This article analyzes the seismic tendency and groundwater changing caused by sea level rise in this area. The results show that sea level rise may lead to serious partial sand soil liquefaction in this area in a hundred years, hut large area sand soil liquefaction is not likely to occur.
