NUMERICAL INVESTIGATION INTO EFFECTS OF LONG FACEBOLTING ON THE PREVENTION OF GROUND SURFACE SETTLEMENT

Abstract

山岳トンネルの補助工法である長尺鏡止めボルトは，切羽の安定対策のみならず，地表面沈下の抑制対策としても採用されているが，長尺鏡止めボルトによる地表面沈下の抑制機構について十分な考察が行われていないのが現状である．本論文では，土被りの小さいトンネルを対象に，三次元数値解析によって，長尺鏡止めボルトによる地表面沈下の抑制効果について検討した結果，砂質土系地山でその効果が大きく，長尺鏡止めボルトは，切羽前方だけでなく切羽から地表面に向かう領域にも応力を拘束し，地表面沈下を抑制する効果があることがわかった．

Keywords

strength parameters, rock reinforcement, ground surface settlement, three-demensional excavation analysis, facebolting
