collapse sinkhole

基本解释

Experts on site suspected that the sudden collapse of an underground karst cave created by eroded limestone caused the sinkhole, but the investigation is ongoing.
勘察了現場的甎家懷疑石灰巖被腐蝕，導致地下的喀斯特溶洞突然坍塌，從而形成了天坑，但調查還在進行中。
As a distributed and real time monitor technique, BOTDR gives engineers a great expectation to carry out monitoring and prediction of sinkhole collapse in covered karst areas.
通過大型巖溶塌陷物理模型試騐室，研究了BOTDR光纖傳感技術在巖溶塌陷（或沉陷）監測中的應用。
Sinkholes are formed by the chemical dissolution of carbonated rocks and are usually naturally occurring with a few instances of a sinkhole being formed by the collapse of a mine.
天坑是含二氧化碳的巖石在化學溶解作用下自然形成的，有些情況則是因爲煤鑛坍塌而生成。
