specific Embodiment

[0055] Step 1: Construct the construction quality evaluation index system of RCC dams based on real-time monitoring system, on-site inspection, sampling inspection and drilling coring. Such as figure 1 As shown, the first layer is the evaluation target layer, that is, the comprehensive evaluation result of the construction quality of the roller compacted concrete dam; Characterization of shear strength and permeability coefficient; the third layer is the parameter layer that affects the quality of compaction and interlayer bonding, including rolling parameters such as: rolling speed v, number of rolling passes n and compaction thickness h, concrete property parameters such as : VC value, Gs value and aggregate gradation, interval time T between layers and degree of compaction p.

[0056] 1) Real-time monitoring technology is used to obtain rolling parameters at any position, and at the same time, the interval time between layers can be obtained. Rolling parameter is an impor...

Abstract

The invention discloses an integrated roller compacted concrete dam construction quality evaluation method taking regard of parameter uncertainty. The method comprises steps that firstly, a roller compacted concrete dam construction quality evaluation index system is constructed, secondly, a compactness nonlinear regression model and an interlayer combination quality index nonlinear regression model are established, thirdly, concrete attribute parameter uncertainty of a roller compacted concrete dam is processed, and a roller compacted concrete dam construction quality evaluation model based on the blind number theory is established; and lastly, integrated roller compacted concrete dam construction quality evaluation is carried out. The method is advantaged in that further development of construction quality evaluation researches is facilitated, a matching degree between the acquired evaluation result and an actual situation is relatively high; based on mathematics uncertainty, influence of compactness quality and interlayer combination quality on construction quality is considered, integrated evaluation on dam surface construction quality is realized, and an effective technical means is provided for construction quality control.

Description

technical field [0001] The invention belongs to the technical field of quality evaluation of roller compacted concrete dams, in particular to a method for comprehensive evaluation of construction quality of roller compacted concrete dams considering parameter uncertainty, and in particular to a method that simultaneously considers compaction quality, interlayer bonding quality and parameter uncertainty A comprehensive evaluation method for construction quality of roller compacted concrete dams. Background technique [0002] The dam construction technology of the roller compacted concrete dam was first proposed by Laphael of the United States in 1970. Because this dam shape has the advantages of fast construction speed, low construction cost, and saving cement, it is widely used in many countries and regions, and how to reasonably control its construction quality has become a research hotspot. The construction method of roller compacted concrete is to compact the ultra-dry a...
