【摘要】：在眾多邊坡穩(wěn)定性中,紅砂巖邊坡穩(wěn)定性是建設(shè)過(guò)程中面臨的一個(gè)大問(wèn)題,紅砂巖由于其經(jīng)過(guò)風(fēng)化作用過(guò)程中的差異性造成其不完全一樣的特殊性質(zhì),含水量有差異的紅砂巖形成其強(qiáng)度同樣存在差別,在接觸水后,會(huì)容易產(chǎn)生崩解,軟化,當(dāng)坡體開(kāi)挖后,會(huì)產(chǎn)生穩(wěn)定性能力不強(qiáng)現(xiàn)象,加上本文工程背景地處亞熱帶氣候,溫度、濕度等因素對(duì)于紅砂巖的地下層巖石性質(zhì)方面的影響會(huì)更加明顯。本文以?shī)涞字梁怅?yáng)高速公路內(nèi)的紅砂巖路塹邊坡為工程背景,通過(guò)對(duì)婁衡高速區(qū)域地形地貌、地層巖性和水文地質(zhì)條件的調(diào)查研究,再結(jié)合該地區(qū)紅砂巖特殊的工程地質(zhì)特點(diǎn),分析出紅砂巖的巖性特征和內(nèi)部存在的破壞機(jī)理,在此基礎(chǔ)上,通過(guò)巖石耐崩解性實(shí)驗(yàn)掌握巖石的崩解數(shù)量、崩解指數(shù)、崩解時(shí)間和崩解狀況,以此研究適合婁衡高速紅砂巖路塹邊坡的具體治理處治方案,加強(qiáng)路塹邊坡的穩(wěn)定性。通過(guò)本文的研究,為婁底至衡陽(yáng)高速公路內(nèi)的紅砂巖路塹邊坡問(wèn)題提供一定的處治措施,以此提高邊坡的穩(wěn)定性,對(duì)日后的安全施工和經(jīng)營(yíng)維護(hù)打下良好的基礎(chǔ)。
[Abstract]:Among the many slope stability, the stability of red sandstone slope is a big problem in the process of construction. Due to the difference in the process of weathering, the red sandstone is not exactly the same special property.The strength of red sandstone with different water content is also different. After contact with water, it is easy to collapse and soften. When the slope body is excavated, the phenomenon of weak stability will occur, and the engineering background of this paper is located in the subtropical climate.The effect of temperature and humidity on the rock properties of red sandstone is more obvious.In this paper, taking the red sandstone cutting slope in Loudi to Hengyang expressway as the engineering background, through the investigation and study of the landform, stratigraphic lithology and hydrogeological conditions of Louheng high-speed area, and combining with the special engineering geological characteristics of red sandstone in this area,The lithologic characteristics and internal failure mechanism of red sandstone are analyzed. On the basis of these, the quantity, index, time and condition of rock disintegration are obtained by rock disintegration resistance experiment.This study is suitable for Louheng high-speed red sandstone cutting slope treatment scheme to strengthen the stability of cutting slope.Through the research of this paper, it provides certain treatment measures for the red sandstone cutting slope in Loudi to Hengyang expressway, so as to improve the stability of the slope and lay a good foundation for the safe construction and operation and maintenance in the future.
