Abstract

It is very important to get the accurate calculation of pit-excavation volume in many civil engineering projects. There have been common drawbacks to earlier methods of ground profiling, such dealing with sharp corners or the grid points any two straight lines. There are several papers of using spline surfaces to obtain more accurate calculations of the earthwork. In this paper, we propose an algorithm of finding a spline surface without boundary conditions which interpolates the given data and an appropriate method to calculate the earthwork. We present some computational results showing that our proposed method provides good accuracy.

건설시공현장에서 토공량 결정에 대한 정확한 계산은 매우 중요하다. 지금까지의 방법은 예리한 코너부분이나 두 직선 사이의 격자점이 있을 경우 지형변화에 대처할 수 없는 결점을 가지고 있다. 이 연구는 좀 더 정확한 토공량의 계산을 위하여 스플라인을 이용한 방법들이 연구되었다. 본 논문에서는 주어진 데이터를 지나고 경계조건이 없는 스플라인 곡명을 구하는 알고리즘을 살펴보고, 이를 이용한 근사적인 토공량 결정 방법을 제시한다.
