Strong earthquake area energy dissipation type pile anchor structure and construction method thereof
The invention discloses a strong earthquake area energy dissipation type pile anchor structure and a construction method thereof, and the strong earthquake area energy dissipation type pile anchor structure comprises energy dissipation anchor cables, anti-slide piles and flexible baffles. The multiple anti-slide piles are arranged on the outer side of a rock-soil body at equal intervals, and the flexible baffles are connected between the multiple anti-slide piles and the side wall of the rock-soil body. The multiple energy dissipation anchor cables are anchored on the anti-slide piles, anchoring sections of the energy dissipation anchor cables are anchored in the rock-soil body, and free sections of the energy dissipation anchor cables penetrate through the flexible baffles and the anti-slide piles and extend out of the anti-slide piles. And the other ends of the free sections are anchored on soil anti-slide piles. And stop-grouting plugs are arranged on the energy dissipation anchor cables and located at the boundary of the anchoring sections and the free sections. Through optimized combination of various energy dissipation components, brittle failure caused by earthquakes is changed into ductility, potential safety hazards caused by instability, collapse, landslide and the like of high and steep slopes in a strong earthquake area to highway and railway construction and vehicle running are prevented, and the stability and the shock resistance of the pile anchor structure are effectively improved.
本发明公开了一种强震区消能型桩锚结构及其施工方法，一种强震区消能型桩锚结构，包括消能锚索、抗滑桩和柔性挡板。若干抗滑桩等间距布置在岩土体的外侧，若干抗滑桩与岩土体的侧壁之间连接有柔性挡板。抗滑桩上锚固有若干消能锚索，消能锚索的锚固段锚固在岩土体内，自由段穿过柔性挡板和抗滑桩并伸出抗滑桩。自由段另一端锚固在土抗滑桩上。消能锚索上设置有止浆塞，止浆塞位于锚固段和自由段的分界处。本发明通过多种消能构件的优化组合，使地震造成的脆性破坏变成延性，既防止了强震区高陡边坡失稳、崩塌、滑坡等对公路、铁路建设、车辆行驶造成的安全隐患，又有效地提高了桩锚结构的稳定性及抗震能力。
