Abstract


Highway in the mountains inevitably there will be a lot of slope engineering . Often leave some engineering risks due to the lack of knowledge of the slope failure mechanism and reinforcement measures ineffective , and a waste of resources . Sea ( the Lanzhou to Haishiwan ) highway construction process in many engineering large-scale , complex factors , geological environment changing slope engineering , where the prevalence of high and steep slope stability and landslide problems of large - scale disasters . Slope engineering stable situation , stabilize the situation , or even a local engineering largely affect investment and efficiency in the use of engineering construction . At present, however, the domestic anchoring technique mostly concentrated in the rock mass slope anchorage mechanism (especially some new anchorage measures , such as prestressed - cable , etc.) to the lack of research , and its applications are mostly based on the soil slope experienced . The detailed analysis of slope failure modes and influencing factors , discusses the slope stability analysis method . Combination of the anchoring technology features , CABLE BEAM internal force calculation mode and slope simplified model of anchoring equivalent parameters derived by theoretical analysis . Prestressed - cable construction complex technical requirements , the analysis of the main problems in the construction process and precautions relying on specific projects - the Sea Expressway K21 segment disease control engineering high slope combined the basic anchoring in reinforcement theory , a systematic study on the high slopes disease remediation process , the proposed technical parameters and safety measures . Through the work site anchor cable the uplift test and anchoring effect analysis , engineering with good results for such slope anchor design parameters .
