作者对泰国与日本形成鲜明对比的自然地貌所构成的边坡失稳问题感兴趣，并对泰国南部的纳孔西塔马拉特进行了研究，结果表明：1）泰国暴雨引起的边坡失稳有受地形地貌控制的趋势;（2）调查区表层土壤分为深层风化红壤和浅层弱风化白壤两种类型。3）X射线衍射分析结果表明，边坡破坏物质中富含高岭石。
The writers have an interest in the slope failures in Thailand which consist of the natural features contrast in a striking way with Japan, and researched them on Nakhon Si Thammarat in the southern part of Thailand, The results are as follows.1) The slope failures caused by a heavy rain storm in Thailand show a tendency to be controlled by the topographical features; zero or first order stream, front of erosion, function of watershed and others.2) Surface soil of a surveyed area includes two types: deep weathering red soil and shallow weak weathering whitish soil. The slope failures occurred in both types.3) The slope failure materials are rich in Kaolinite on the basis of results of an X-ray diffraction analysis.
