Slope greening is an important part of road engineering construction. Its main purpose is to improve the ecological environment on the side of the road and improve its ability to resist geological disasters.The engineering features of this paper are long road engineering, large area of slope treatment. It analyzes the technical difficulties in the construction of slope greening project, such as large excavation depth, more stone slopes along the road, serious exfoliation of external soil and less nutrients in the soil. In view of the above technical difficulties, the key construction techniques such as excavation and filling slope construction, external soil direct seeding, spray seeding of external soil with hanging net, slope maintenance, combination of skeleton protection and plant slope protection are studied. It ensured the quality of the project and provided reference for the construction of related projects.

Objective To study the early predictive value of cord blood bilirubin and dynamic monitoring of transcutaneous bilirubin for hyperbilirubinemia of newborns. Methods 389 newborns delivered from June 2014 to December 2015 were enrolled as the research subjects; detailed records were made about the general data of newborns and mothers, and after cord blood bilirubin being graded, the incidence of hyperbilirubinemia was counted, and the prediction efficiency of cord blood bilirubin was analyzed by receiver operator characteristic (ROC) curve. At the same time, the transcutaneous bilirubin was detected continuously when the neonate was born and 24 h, 48 h and 72 h after birth, and the relativity between transcutaneous bilirubin at 72 h and serum bilirubin was analyzed. Results No significant difference was found in the hyperbilirubinemia group and the non-hyperbilirubinemia group concerning general data of the newborns and their mothers. With the concentration of cord blood bilirubin increased, the incidence of hyperbilirubinemia also increased; separate prediction of hyperbilirubinemia by cord blood bilirubin showed a sensitivity and specificity of 71.4% and 65.6% respectively, and they need further dynamic monitoring. The daily mean of transcutaneous bilirubin in hyperbilirubinemia group was significantly higher than that in non-hyperbilirubinemia group at 24 h, 48 h and 72 h, and the measurement value of transcutaneous bilirubin at 72 h had a high correlation with serum bilirubin. When transcutaneous bilirubin value is higher than 18, the incidence of hyperbilirubinemia should be considered. Conclusions The increase of cord blood bilirubin effectively predict the occurrence of neonatal hyperbilirubinemia. There is a good correlation between levels of transcutaneous bilirubin and serum bilirubin. Moreover, combined detection of transcutaneous bilirubin and cord blood bilirubin can significantly improve the prediction accuracy of hyperbilirubinemia.

Based on the study of theoretical research of fuzzy neural network, this article focuses on neural network-based durability evaluation system of reinforced concrete bridge to construct the key technologies. It clarifies principle process of durability evaluation, determines membership function form in evaluating index and puts forward a method of fuzzy cluster and neural network-based bridge durability status evaluation. The simulation analysis shows that this method fully utilizes data characteristics and reduces the effect of artificially judging subjective factors. It can fully apply monitoring data of bridge health and improve effectiveness and objectiveness in bridge durability status evaluation.
