本文结合深圳坪山至西冲一级公路中的雷公山隧道工程实践情况，对隧道超前支护预加固技术和初期支护施工技术进行了深入的探讨。 |
| 6. | Its conclusion that shell was better than cable for preventing destroy of surrounding rock . shearing destroy are reduced obviously with enhanced support . ( 8 ) by monitoring and numerical analyzing , it concluded that the deformation field of surrounding rock went to stabilization after first support
( 8 )通过监测和数值分析可知，初期支护施工一段时间后，围岩变形逐渐趋于稳定，监测锚杆最大受力为80kn ( 200mpa )其最小安全系数为1 . 7 。 |
| 7. | The use of shotcrete as early linings of tunnel is a prevalent technique in underground engineering today . in cases with reliable rock situation , shotcrete linings can even be used as permanent prop for tunnel . the sfrc can act as a substitute for normal concrete and yields good results in such situation
以喷射混凝土作为隧道初期支护是隧道工程实践中一项较成熟的技术，在围岩条件较好的一些工程中，喷射混凝土衬砌甚至可以单独作为永久的衬砌使用。 |
| 8. | This thesis pass through the laser delimitation instrument and the geological radar instrument means , to tunnel initial stages support and secondary structure . at past the research of tunnel lining thickness depend on opening dig figure , don " t consider the effect of tunnel lining inner figure . adopting the integrate method of the laser delimitation instrument and the geological radar could most exact reflect the change rule of tunnel lining thickness , but also could do lots unbroken examination , have very important for summing - up the rule of tunnel lining thickness change , and have very amplitude extend value
本文通过激光限界仪和地质雷达综合方法，对新建高速公路隧道初期支护和二次衬砌混凝土内轮廓和厚度进行了检测，对衬砌厚度的分布规律以往的研究中，多以开挖和衬砌的轮廓变化为依据，并未考虑衬砌内轮廓的影响，而采用激光断面轮廓限界仪和地质雷达综合方法能较为准确的反应衬砌厚度的变化规律，并且能够无破损的做大量的检测工作，为总结混凝土厚度的规律有很大作用，并有极大的推广价值。 |
| 9. | Finally , the thesis primarily sets up the internal force model of the supporting structure system in the bi - arch tunnel , namely , the distribution model of the surrounding rock ' s pressure , the internal force model of the steel framework and the axial force model of the anchor bolt , and these results can have the guiding significance to the design and construction of the similar tunnel engineering
最后，结合有限元的理论计算及现场实测数据的分析，初步建立了双连拱隧道支护结构体系的内力模型，即：围岩土压力模型、初期支护钢拱架内力(主要为轴力和弯矩)模型以及锚杆轴力模型。充分理解和阐述了构件的工作状态，对今后类似隧道工程的设计和施工具有一定的指导意义。 |
| 10. | In order to assure the stability of surrounding rock and initial supports , construction monitor procedure is designed . the method for field survey , data processing , rock stability censoring and unstable rock controlling are also provided in the thesis to ensure the efficiency of the construction
为保证施工过程中围岩与初期支护的稳定性，进行了施工监控量测设计，确定监控量测的项目、现场监控量测的方法、量测数据的处理、围岩稳定性判断及控制围岩失稳的对策。 |
