土地整理中大面积土方工程几种最优计划高的计算方法

在土地整理工程中涉及到大面积土方工程,在不同条件下,有着不同的计划高。该文在保加利亚留保米尔教授关于不受任何条件限制下的最优计划高计算的理论基础上,提出了5种不同的特定条件下最优计划高的理论计算方法。采用这些计算方法计算计划高,在原定条件下,土方量将是最小的,而且计算也较简便

Calculation Method of the Optimum Planned-Elevation for Bulk Wide Area Earthwork in land Consolidation

In different conditions, there are different planned elevations for the bulk wide area earthwork. On the basis of theory presented by professor Leiboumils (Bulgarian), with respect to calculation of the optimum planned elevation which is not subject to any condition, five theorical formulae for calculating the optimum planned elevation in different special conditions are suggested: first, the distance of each point is equal in the ground of square; second, the planned area without retaining a height of given point (P); third, the planned area must retain a inclined angle in one direction; fourth, the planned area must retain the height h₁ and h₂ for two given points; fifth, the planned area must retain horizontal. In this way, the volume of earthwork can be the least and the calculation can also be simpler if calculation is made in accordance with the formulae under the original condition.
