The Study On Analysis Of The Effect Of Surcharge Load On Subsoil

ABSTRAC:The topic comes from to make use of bridge to descend the space heap in the big bridge construction process put sand, stone etc., the building material and construction garbage bring of engineering problem. According to theories analysis, prognosticate to tally up with the engineering experience on the scene, combine related norm, at big bridge descend soft soil foundation last carry the influence of the analysis to the stake, get is relevant conclusion. The Anne's big bridge descend for the soft soil foundation, last carry to the nearby pillar in the soft soil foundation under of the stake exist disadvantageous influence, have to control to gather to anticipate strictly of the heap put height; big bridge descend soft soil foundation last carry to cause foundation to sink to decline is the process of the gradual development and what to transform, have to strengthen a monitor, raise the monitor accuracy as far as possible loading dint of the soft soil foundation has something to do with soft soil of naturally containing amount of water, stake the will be subjected to a bigger side toward the function of the dint, producing the bigger level to the on the stage gathers to anticipate self-respect with the additional is toward the lotus carry a form directly deliver the outside of the to stake, the bridge descends soft soil foundation last carry will cause a stake a week a soil body to press airtight sink to decline, the soil body sinks to decline to have great capacity in the stake sink to decline quantity, produce to the negative friction of the stake, also with the additional is toward the lotus carry of form function in stake body, these two kinds of additional s toward the lotus carry of function will make to anticipate a heap stake that carries a neighborhood to sink to decline the stake that the speed compares other parts quick, this kind of asymmetry sink to decline the upper part structure that will influence. The heap of the soft soil foundation carries to make the soil body occurrence sink to decline not only, will also cause the side of the soil body to flow, produce the side pressure to the nearby stake, make a creation move. big bridge is next to put to gather to anticipate of safe height with biggest the height is the 3.46 ms and 4.85 ms.
