摘　　要：本文运用岩石力学、岩石矿物学、地质构造学的理论和方法,以静力载荷试验、沉降观测为主要手段、初步总结出青岛市区花岗岩强风化带的容许承载力一般为600～2800kPa。此外,本文还初步总结了采用"定量法"对花岗岩风化带进行划分的一些尝试,并提出以强风化带作地基的建筑预估沉降量计算的借用公式。上述成果在岩土工程中得到广泛的运用,并取得了显著的经济效果。An initial conclusion that the allowable bearing capacity of strong weathering zone of granite in urban area of Qingdao City is generally 600-2800Kpa is made in this article by applying the theories and methods of rock mechanics, rock mineralogy and tectonics, and by using static loading test and settlement observaion as the major measures. Moreover, attempts for the granite weathering zones differentiating by 'quantitative method' are also summarized, and formula for predicting settlement of buildings erected on strong weathering zone is also proposed. The adove mentioned results have been widely used in geotechnical engineering and remarkable economic results have been achieved.
