Slope stability bidimensional analysis in a geological fault zone in Chinchao, Huanuco, Peru

Jose Antonio Bustillos Cotrado — 2024-01-24

Objective. Evaluate slope stability condition in a geological fault zone through the limit balance method of the progressive of the highway, km 37+700 al km 37+800 (national route PE+18A), of the populated center Pachachupan, Chinchao district, provin-ce and region Huanuco. Methods. Research quantitative ap-proach descriptive level naturalistic observation type basic and no experimental. The sample consisted of the most critical slope using a nonprobabilistic purposive sampling criterion. Results. The factor of safety for the static analysis was 0.381 and for the pseudo-static analysis 0.214. On the other hand, the geo-logical fault was found inactive, presenting as direct indicators: displacements of 5.5 cm in the fault plane; striations in the di-rection of the fault plane of 2 to 2.5 cm; fault breccias in eroded depressions of fine material and direct indicators; a morphology of steep area by erosive processes with view of fractures in the strata of the rock massif; vegetation consisting of shrubs and cultivated agricultural land; and absence of tributaries and torrents generated by groundwater. Conclusions. The slope stability condition for a static and pseudo-static analysis was unstable and the inactivity of the geologic fault does not represent a critical potential risk in the formation of external geodynamic phenomena (landslides, earth flows and debris flows).

Urban geography and tourist enclaves of the district of Huánuco

Esli Ruth Vasquez Huamancaja — 2024-01-24

Objective. Knowing the urban geographic composition of the district of Huánuco, focusing on cultural agents and tourist enclaves. Methods. The methodology developed used spatial representation and analysis tools, with satellite images. Results. It was identified that the tourist spaces in the district of Huanuco reveal that the fracture of the tourist landscape units, according to land use, manage to introduce diversity and cultural differences, rather than monotony and uniformity. Conclusions.The enclave tourist spots emerge as fractured, excluding and protected landscapes; in this way they encapsulate an intimate concept of the district of Huánuco.

Perceptives maps in the informality and insecurity context in Las Moras, Huanuco, Perú

Jhon Guerra Alvarado — 2024-02-03

Objective. Analyzing the synergistic relationships between segregation, security and public space in the Las Moras populated center. Methods. Qualitative approach, realized as of surveys applied in the virtual participatory workshops; beside, a visual perception analysis as of were obtained perceptive maps that allow to know the visual and subjective representation of the place. Results. Populated center residents perceive insecurity; in the same way, urban segregation exists, and that public spaces are minimally used by the population. Conclusion. The existence of urban segregation is evidenced, as a product of which a growing urban duality is generated.

Soils fertility of San Isidro sector, province of Leoncio Prado, Huanuco, Peru

Yeni Mejia Aguirre — 2024-02-08

Objective. Knowing the chemical fertility of the soil of the San Isidro sector, province of Leoncio Prado and to represent through thematic maps the geographic distribution of soil fertility as a function of physiographic units. Methods. Was made a physiographic map where three physiographic units appear. Three sites were then selected. Sampling for each of these units resulted in a total of nine samples that were taken to the soil laboratory for examination. The results were used to calculate chemical fertility using the methodology proposed by the Agus-tín Codazzi Geographic Institute and were interpolated using ArcGis software. Results. Fertility levels: low in samples 01, 02, 04, 05, 06 and 08; moderate in samples 03, 07 and 09. Regarding spatial distribution, according to the physiographic unit, the highest percentage of low fertility is found in Ma with 51.11 %, then in Ta2 with 9.93 %, and the lowest percentage in Ta1 with 7.17 %. At a moderate level, the highest percentage is also found in Ma with 21.82 %, followed by Ta2 which occupies 8.48 %, and finally and in the lowest percentage it is located in Ta1 with 1.50 % of the total area. Conclusion. The soil fertility found in the San Isidro sector corresponds to low and moderate fertility; and as for the spatial distribution of fertility, the highest percentage is low, with 68.21 % (177.89 ha)

IDAC is a means of scientific dissemination of technical and academic nature, whose subject matter is ascribed to the lines of research of the Faculty of Engineering, made available to the national and international academic community, which strengthens research in the disciplines of architecture, systems engineering and computer science, environmental engineering and civil engineering.

Use of pinus needle fiber to enhance the concrete mechanicals properties: a systematic review

Flor Liliana del Rocío Llenque Galán — 2024-02-12

Objective. Realizing a systematic review about pinus needle fiber added to enhance the mechanical properties of concrete. Methods. A systematic review of 80 articles distributed in indexed databases was applied as follows: 15 from Scopus, 30 from ProQuest, 11 from EBSCO, and 24 ScienceDirect, where 32 articles from 2017 to 2019 and 48 articles from 2020 to 2022 were found. Development. To the articles search were used the next words: pinus fibers, influence of pinus fiber, properties of concrete with fiber, use of pinus fiber. It is found that using 25 % and 50 % of pinus fibers improves the mechanical properties of concrete, increasing by 12.6 % and 15.60 % the compressi-ve strength of concrete. Conclusion. It is concluded that using pinus fiber in concrete can increase the compressive strength as well as increase its ductility and toughness, among other me-chanical properties.
