Assessment on the Safety Risk of Existing Iron Tower Foundation by the Construction of a Pipe Gallery Working Well
Taking the construction of a pipe gallery working well as an example,this paper uses PLAXIS 3D software to establish a three-dimensional model for numerical analysis,and studies the influence of twelve kinds of working conditions on the existing iron tower foundation in the construction of pipe jacking working well.In the construction process of pipe jacking working well,the step that has the greatest influence on the adjacent power transmission tower is the soil reinforcement stage inside and outside the foundation pit.Assessing the existing engineering risk level caused by the engineering can provide reference for the safety assessment of the existing engineering.
