The invention discloses a combined supporting structure for slope protection and improvement of a high-steep reservoir bank soil slope. The combined supporting structure is formed by adopting latticeguest nets and micro piles; the combined supporting structure comprises the micro piles formed by double rows of circular hollow prefabricated steel pipe piles, the micro piles are stretched into a certain depth below the ground, the depth is not less than 3m penetrating through a slope potential slip surface, and crown beams are arranged at the tops of the micro piles to connect the double rows of piles; the lattice guest nets are piled up at the tops of the crown beams, and comprise net bodies, side wires and net wires; and the side wires are arranged on the side parts of the net bodies, andmeshes are arranged between the side wires and the net wires. According to the combined supporting structure formed by the lattice guest nets and the micro piles, the column bottom is stretched intoa certain depth below the slope potential slip surface, the building-in segment lengths of the piles are ensured, the whole stability of the slope is enhanced, the lattice guest nets take the crown beams as foundations, the self loads of the lattice guest nets are transmitted into a lower stable rock soil layer through the pile bodies, so that the pulling, cracking and transformation of the lattice guest nets cannot happen due to poor foundation bearing force, and the self whole stability of the lattice guest nets is ensured; and meanwhile, the lattice guest nets have high anti-corrosive property and tensile strength, the long-term and stable operation of the high-steep reservoir bank soil slope after the improvement can be ensured, and the high-steep reservoir bank soil slope improvementeffect is good.
本发明公开了一种用于高陡库岸土质边坡护坡整治的联合支护结构，该联合支护结构是采用格宾网+微型桩构成的；包括由双排圆形中空预制钢管桩构成的微型桩，该微型桩伸入地面以下一定深度，该深度穿过边坡潜在滑裂面以下不小于3m，微型桩顶部设置冠梁将双排桩连接起来；在所述冠梁顶部堆砌设有格宾网，格宾网包括网体、边丝和网丝；网体边部设有边丝、边丝与网丝之间设有网片。本发明所形成的格宾网+微型桩联合支护结构，桩底伸入边坡潜在滑裂面以下一定深度，既保证了桩的嵌固段长度，又使得边坡的整体稳定性得到了加强，格宾网以冠梁顶为基础，格宾网自重荷载通过桩身传递至下部稳定岩土层内，这样格宾网不会因为地基承载力不足而发生拉裂变形，保证了格宾网自身整体稳定性；同时，格宾网具有更高的抗腐蚀性、抗拉强度，可保证库岸高边坡整治后的长期稳定运营，用于库岸高边坡整治效果更好。
