近些年来,随着城市建设的迅速发展,建筑场地日趋紧张,以往被认为不宜建筑、地形地质条件差的场地,如沟塘、低洼且被垃圾堆积的场地等,也不得不加以利用。因此勘察面临的新任务之一是:要对其工程地质条件比较复杂的地基进行认真的调查和试验研究,作出正确的岩土工程评价,以便选择合理的地基处理和基础设计方案。 In recent years, with the rapid development of urban construction, construction sites have become increasingly tense. In the past, sites that were deemed unsuitable for construction and had poor topographic and geological conditions, such as ditch and ponds, low-lying and waste-disposal sites, had to be used. Therefore, one of the new tasks faced by the survey is to seriously investigate and test the foundations with more complex engineering geological conditions, and to make correct geotechnical engineering evaluations in order to select a reasonable foundation treatment and basic design scheme.
