摘　　要：公路下伏废弃立井时,可采用半球面混凝土盖帽处理废弃立井,为了方便设计半球面混凝土盖帽,本文提出将半球面混凝土盖帽简化为半圆形拱进行设计,并用力法推导了计算公式,利用公式分别设计了不同填土厚度下半球面混凝土盖帽,并用Ansys计算验证了该设计方法的可行性,可以在工程中推广应用。When abandoned shafts are buried under highways,hemispherical concrete caps can be used to treat abandoned shafts.In order to facilitate the design of hemispherical concrete caps,this paper proposes to simplify the design of hemispherical concrete caps to semi-circular arches,and derives a calculation formula using the force method.The hemispherical concrete caps with different fill thicknesses are designed using the formula,and the feasibility of this design method is verified using Ansys calculation.It can be promoted and applied in engineering.
