承压含水层在2018 年 9 月 28 日帕卢(印度尼西亚)7.5 Mw地震引起的土壤液化机制中的作用

Relief well as liquefaction mitigation option in Mpanau, Sigi, Central Sulawesi, Indonesia

“…The findings revealed that the water surface is shallow with loose sand, indicating a significant potential for liquefaction across all these points[7].Liquefaction mitigation has been discussed by several studies on the Gumbasa Canal, one of which is the use of impermeable layers[8]. Meanwhile, the influence of aquifers on liquefaction is hypothesized based on oral sources immediately after the earthquake[9]. A seepage analysis is used to determine whether or not a relief well is required, and it also gives the requirements for the construction of a relief well system.…”
