去年夏天,正在施工中的上海轨道交通4号线发现渗水,随后出现大量流沙涌入,引起地面大幅沉降,并导致地面建筑物一幢八层楼房发生倾斜,其裙房部分倒塌。
Last summer, water seepage was found on Shanghai Metro Line 4 under construction. A large influx of quicksand followed that caused a drastic ground settlement and led to the tilt of an eight-storey building on the ground and its podium partially collapsed.
