Embodiment Construction
[0012] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail
[0013] Such as figure 1 Shown, natural soft soil foundation riprap backfill engineering quantity analysis calculation method of the present invention comprises the steps:
[0014] (1) Analysis of geotechnical engineering conditions: Select typical construction areas with different geotechnical engineering conditions as the subject test area, and at least two subject test areas with different engineering conditions are selected.
[0015] (2) Contrastive analysis of the engineering quantity of the drawings and the actual quantity of throwing and filling: analyze and study the main factors and the degree of influence that affect the difference between the actual throwing and filling quantity and the engineering quantity of the drawings, and find the calculation quantity suitable for the drawings in the throwing and filling project in this project area The c...

The invention discloses a method for analyzing and calculating the project quantity of riprap backfilling on a natural soft soil foundation, which comprises the following steps: (1) analyzing the conditions of geotechnical engineering; It is suitable for the difference coefficient between the calculated amount of drawings and the actual amount of dumping and filling works in this project area; (3) when the land push operation is carried out on the soft soil foundation in this project area, when the boundary conditions are met: the actual amount of dumping and filling The relationship between the engineering quantity of the drawing can be expressed by the empirical formula as follows: V actual throw amount = V2 + S × h measured settlement, where: V2 is the earthwork volume calculated on the drawing, and S is the backfill area. The present invention provides a basis closer to reality in the balance of stone materials for mountain opening and backfilling under similar conditions, provides a more practical guidance basis for resource allocation in construction organization, and provides a time-saving and cost-saving solution for project measurement and completion settlement. new method.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an analysis and calculation method capable of estimating the actual natural soft soil foundation riprap backfill engineering quantity. Background technique [0002] Whether the calculation of the project volume of natural soft soil foundation throwing and filling conforms to the reality has a great influence on the balance of earthwork before construction, the manpower, equipment, vehicle equipment and project measurement in construction organization, and the accuracy of project price settlement after completion. Since there is no suitable calculation method for reference at present, it is difficult to arrange relevant work based on the calculation amount of drawings before the project, which brings great difficulties to engineering measurement, investment control, and settlement. [0003] Therefore, it is necessary to provide a calculation method that c...
