According to the geological characteristics and the surrounding environment of the proposed field area, based on the safe, reliable, economic and viable principles, this paper established the pile anchor. For the severe collapse hole phenomena, it should first use the high pressure jet grouting for anchor soil reinforcement to achieve sealing and reinforcing role, and then conduct the hole construction anchor.%根据拟建场区的地质特点和周边的环境，本着安全可靠、经济可行的原则设立排桩锚杆。对严重塌孔现象需先采用高压旋喷加固锚固土体，以达到止水和加固土体的作用，然后再成孔施工锚杆。
