摘要
对某建筑物场地进行详细勘察的基础上，运用X－衍射、差热分析、透射电子显微镜等微观分析手段和室内常规水理性质实验方法，对场地内③、④层粘土的胀缩性能（机理）进行了详细分析与评价；论述了膨胀土地基上建筑物开裂破坏形式、引起开裂的工程地质条件，并对导致建筑物开裂的内、外因素进行了分析。
On the basis of the detailed investigation on a building site, the expansive and compressive mechanism of the third clay and fourth one in the site is discussed and appraised by the microcosmic analysis methods, such as X-diffraction, differential heat analysis, transmission electron microscope etc, and general indoor experimental methods of hydrological properties. The fracturing pattern of a building on expansive soil foundation and the geotechnical conditions of building crack are expounded, and their internal and external factors are analysed.
