膨胀土地基工程地质分析专家系统(ESCES)

在中国南方地区膨胀土地基工程地质研究基础上,概括了国内外知名学者的研究成果,进行了土体结构的工程地质力学分析,归纳成近千条规则,设计并建立了膨胀土地基的专家系统。它包括膨胀土类型鉴别,胀缩特性判定,膨胀恶化预测,地基工程结构选定和基坑边坡稳定性评价等内容。本专家系统在河北、湖北、广西等四个不同地区的工程中得到验证,表明它是解决复杂的膨胀土地基问题及推动膨胀土工程地质研究的一种有效手段。

AN EXPERT SYSTEM FOR ENGINEERING GEOLOGICAL EVALUATION (ESCES) OF FOUNDATION ON EXPANSIVE SOIL

On the basis of comprehensive study of expansive soil in southern China, particularly in the Guangxi Zhuang Autonomous Region and Yunnan Province, the authors, summarizing theoretical concepts and practical experiences gained by about 30 well-known experts in the field, obtained nearly one thousand rules and established a knowledge-based expert system. It contains classification of expansive soil, determination of engineering properties, prediction of swelling deterioration, selection of site and type of foundation structure, and evaluation of slope stability, forming an unique computer system. The tested results by using the system for 4 construction projects in Hebei, Hubei and Guangxi Provinces show that the proposed expert system is and effective tool for engineering geologists and geotechnical engineers in solving complex problems of foundation on expansive soil and could serve as an active promotion in its engineering geological study.
