Abstract EN
The durability of lightweight cellular concrete (LCC) and the corresponding assessment method are studied in this paper to improve the utilization of LCC in subgrade construction engineering.
The durability assessment method is established by combining the analytic hierarchy process (AHP) with fuzzy comprehensive evaluation (FCE).
The main assessment processes are as follows.
Firstly, based on the physical and mechanical properties of LCC, the influencing factors are selected in terms of preliminary design, construction technology, and operation and management after completion of construction.
The grading standard of influencing factors is established as well.
Secondly, a multilevel assessment model with targets level, criteria level, and indexes level is established.
AHP determines the effective weight of the lower level relative to the upper level.
The consistency check of the judgment matrix is conducted to prove the rationality of the distribution of influencing factors’ effect weight.
Thirdly, the membership function which is suitable for each influencing factor is built to calculate the membership degree.
Besides, the practicality and reliability of AHP combined with FCE are demonstrated through a practical engineering case, which is the third section of a highway in Guangdong Province, China.
