Sandy dolomite strata are widely distributed in the diversion tunnel of Yuxi section Water Diversion Project Central Yunnan (WDPCY). The water-sand inrush is main failure phenomenon construction sandy tunnel, which has seriously and commonly threatened safety Chenaju (CNJ) WDPCY. In this paper, we established discriminant matrix risk assessment by consulting experts, including designers personnel CNJ tunnel. Then, carried out based on proposed Fuzzy-AHP method. results show that (1) a...
Studying the deformation and failure mechanism of Tanziyan landslide in Yesanguan Town, Badong County, designing controlling measures are great significance to ensure sustainable development urban planning construction. In this paper, stability is analyzed using calculation method complex plane slip surface. After consideration essential characteristics disaster body,the studied, corresponding treatment presented. Results show state understable unstable as a whole, process can be roughly...
Although disintegrated dolomite, widely distributed across the globe, has conventionally been a focus of research in underground engineering, issue slope stability issues dolomite strata is gaining increasing prominence. This primarily due to their unique properties, including low strength and loose structure. Current methods for evaluating stability, such as basic quality (BQ) probability classification (SSPC), do not adequately account poor integrity structural fragmentation characteristic...
Excavation damaged zones (EDZs) in deeply buried underground powerhouse have become major obstacles to design and support, which potentially threaten safety stability increase construction support costs. In this study, investigations of the EDZs were performed by applying an acoustic velocity detecting method Houziyan hydropower project, southwest China. A total 38 testing boreholes distributed high sidewalls main carried out, corresponding 153 curves obtained analyzed. Then, divided into...
Cataclastic rock masses with multiple failure modes and mechanisms are critical geological problems in the construction of slopes. widely distributed slopes a hydropower project located on Lancang River, which is Tibet, China. In this study, potentially unstable block slope divided into key secondary based theory, system reliability evaluation theory introduced. The method for quantitatively analyzing mass stability cataclastic sliding established. Then, spatial distribution discontinuities...
Dangerous rock mass in the overhanging slope of Puerdu town has good free‐face condition, high position, and great potential energy, identification stability evaluation which is a difficult problem disaster prevention. In this paper, limit equilibrium method was used to evaluate dangerous slope. Firstly, geomorphic characteristics distribution are determined by field geological survey. Secondly, six masses may cause more threat studied, with defining their failure modes characteristic...
The stability of high rock slopes has become a key engineering geological problem in the construction important projects mountainous areas. original slope probability classification (SSPC) system, presented by Hack, made obvious progress and been widely used analysis. However, selection determination some evaluation indexes SSPC method are usually subjective, such as intact strength weathering degree. In this study, based on data obtained prospecting tunnels was applied. According to field...
Analysis of the movement trajectory and risk assessment high‐slope dangerous rock mass collapse are great significance for preventing controlling geological disasters collapse. This study firstly takes high slope in Pu’erdu Town, Yanjin County, Zhaotong City, Yunnan Province, as research object, calculates analyzes several groups with threat, RocFall used to carry out numerical simulation analysis verification. Secondly, vulnerability area analyzed, evaluation is carried through matrix...
Abstract The sericite schist is a typical metamorphic soft rock. Large deformation of surrounding rock often occurs in the construction tunnel this stratum. Due to broken mass structure and poor mechanical strength Baishitou project Dalin line Southwest railway, it impossible prepare standard samples for traditional test. Therefore, we chose penetrometer (SH-70) an situ Firstly, monitored sections analyzed characteristics large tunnel. Secondly, tested needle penetration index fresh...
