| 摘 要： | 残积土作为一种特殊土,其工程地质性质往往因母岩类型、地质环境及风化条件的不同差异很大。该文通过对野外资料、室内试验及原位测试等手段所获得的大量数据的整理分析,对日照市区花岗岩残积土的工程地质性质进行了初步研究,论述了日照市区花岗岩残积土的成因、分布、工程地质性质以及工程建设中残积土利用的问题。在残积土物理、力学性质试验的基础上,结合当地的工程实践经验,提出了花岗岩残积土的压缩模量（Es）、地基承载力特征值（fak）等物理力学指标的建议值,为日照市城市建设的发展提供了一定的地质依据。

| Abstract: | As a special soil, geo--engineering properties have great differences due to country rock types, geological environment and different weathering conditions. Through analysis on large amount of datas gained from field information, laboratory test and original location testing, geo--engineering properties, as wll as problems occurred in engineer eonstruciton are studied as well. On the basis of physical and chemical experiments modulus （Es）, the foundation bearing capacity value （fak） and other physical and mechanical indicators are put forward which will provide geological basis for the development of urban construction in Rizhao city. |
