局部超载与基坑变形相互影响的初步研究

Research of interaction between part overloading and deformation of deep excavation

依据布西奈斯克解分析计算了超载引起的土体附加应力,并分析了其作用在基坑围护结构时,相对于土体侧应力的影响比例,指出基坑开挖引起周围土体的扰动,作用在扰动土体的超载将会产生额外的沉降,同时探讨了土体扰动下的超载沉降,为类似问题的进一步研究提供了理论基础。

This paper according to J. V. Boussinesq Solution, calculates the add-on soil press caused by overloading, and analyses the rate between overloading and soil, when theY act on undergroud wall simultaneitily. Deep excavation begets disturbance of soil around, overloading acting on the disturbed soil will bring extra settlement, this paper will discuss the settlement caused by overloading acting on the disturbed soil. So to give a theory basis to the further research of the similar problems.
