During the construction of a tunnel, most of a the parameter designs of the third short of adjacent rocks combined bolting and shotcreting are analogical designs based upon the observation of displacements and without any of the effect of surrounding rocks taken into consideration. According to the anchor bar strengthening theory, there will be a strengthened bearing arch in the action area of anchor bars as a result of the combined actions between these bars and shotcrete.

During the construction of a tunnel, most of a the parameter designs of the third short of adjacent rocks combined bolting and shotcreting are analogical designs based upon the observation of displacements and without any of the effect of surrounding rocks taken into consideration. According to the anchor bar strengthening theory, there will be a strengthened bearing arch in the action area of anchor bars as a result of the combined actions between these bars and shotcrete. This bearing arch's depth is in accordance with many factors such as the length,distance of the anchor bars and surrounding rocks' mechanic behaviors. This provides the method to calculate the anchor strengthening action area coefficient K l and design the length of an anchor bar considering the minimum depth of the bearing bar permitted by the stability of the base rocks,K l and the distance between anchor bars. The cost of combined bolting and shotcreting can be reduced by 30%.

国内隧道施工中对于Ⅲ类围岩喷锚支护的参数设计多数是根据围岩位移监测结果,经工程类比确定,没有考虑围岩主体对支护参数的影响。根据锚杆加固机理,从理论上阐述了系统布置锚杆时,由于锚杆和喷射混凝土与围岩的共同作用,在锚杆互相作用影响范围之内将形成一个加固后的承压拱。承压拱的厚度与锚杆的长度、间距、围岩的力学性质等因素有关。给出了锚杆加固影响范围系数K_l的计算方法,并根据围岩稳定所必须形成的承压拱最小厚度、锚杆加固影响范围系数K_l和锚杆的间距来确定锚杆长度的方法。优化后喷锚支护成本可降低30%。

以转基因抗除草剂水稻(Oryzasativassp.japonica)为例,对转基因作物进行安全性评价。对转bar基因水稻进行了基因流动实验、小鼠急性毒性实验、致突变实验和Ames实验。结果表明,转bar基因水稻花粉在5m内有少量的漂移到普通野生稻(O.rufipogon),但没有向其它野生稻(O.officinalis和O.meyeriana)和杂草漂移。小鼠经口急性毒性半数致死量LD50>20g/kg,属实际无急性毒性物质;经微核实验、精子畸变实验及Ames实验均未发现有致突变作用,初步表明转bar基因水稻对小鼠是安全的。
