大型油罐基础砂石土垫层的定量设计与检验

Design and Inspection of the Fixed Quantity of Sand-stone-mud Padding for the Foundation of Large Oil Storage Tank,

油罐基础砂石土垫层是油罐地基发生不均匀沉降的重要因素。文章介绍了一种对大型油罐基础砂石土垫层的设计与检验的方法——K_30试验法。详细叙述了K_30值及其物理意义,对设计需要的K_30值最低限值的确定及K_30值的测试方法做了透彻的论述,并通过实例说明了此方法的准确可靠性。

The sand-stone-mud padding of oil tank foundation is an important factor in uneven settlement of the tank basis. The paper introduces a method, called as K30 testing method, for designing and inspecting the sand-stone-mud padding of large oil storage tank foundation. It explains K30 value and its physical meaning in detail and makes a clear introduction for the determination of minimum K30 limit required in design and for the testing method of K30 value. The method has been proved to be accurate and reliable by a practical example.
