Jinan City, The Typical Formation Deep Foundation Engineering Support Design And Structure Selection Investigate

The development of which has pushed on the devepment of underground space. Now, the underground space of Jinan city various uses gets development to use , such as underground parking places, underground markets, underground storehouse, servant guards against the various underground facilities . The construction of these underground spaces adopts the clear France of digging with cheap cost and convenient construction , has produced plenty of deep base hollow projects from this , and city base hollow project is often in the on the ground architectural and underground dense region of pipeline and construction thing. The works which have been done in this study are as following:Firstly, Combine the environment geology condition with the deep foundation pit engineering characteristics, according to the special engineering geology and the hydrology geology condition of jinan city, divide the line a hard quality soil District and win the hard soil area and weak three types of typical model geologic stratus of soil area.Secondly, through analyzing the area of cent of the deep foundation pit engineering typical model geologic strata of jinan city , tally up the design way of thinking of the south city pit in the usage school design method of jinan city, Compared to introduce the foundation pit engineering the design method that deeply is main to pay to protect the structure completely, and aim at under the different typical model geologic strata condition of jinan city of paid the total way of thinking of protect the structure design to carry on the study, The deep foundation the pit engineering that put forward jinan city designs the process in the problem that should notice.Thirdly, according to the place environment condition,the foundation pit to dig the depth and scale and the place geologic strata structure and the engineering property, for the area of cent that protects the engineering typical model geologic strata of the deep foundation the pit of jinan city, tally up to pay to protect the principle that the structure chooses the type.Fourthly, In regard to the deep foundation pit engineering of jinan city, the influence that solves the very weak soil area foundation pit to decline the water to the periphery environment is heavy to win of heavy, so emphasized the deep foundation the pit engineering of the weak soil area and have to establish the toward the design way of thinking that cuts the water prudes; But the weak soil area pays to protect the structure to choose the type to have the diverse, should synthesize the factor of everyone noodles to carry on to pay to protect the structure to choose the type.Fifthly, through summarizing the design and construction of foundation pits in Jinan city,some perspectives and suggectives which are objective and practical were propsed in this paper.
