Erials, such as instable geltime, low stability, poor underwatererosion resistance and so on, and based on the short geltime features of ordinary cement sodium silicate and alkaliactivated salic cementitious materials, an ideal structure model of high performance sodium silicate suspension twoshot groutingmaterial is established. An experiment is undertaken to verify the solidification value of Na+ and watererosion resistance of a grouting material combined with cement and metakaolinsodium silicate. This paper puts forward a compact structure with a dominant ingredient of—Si—Al—H zeolite gel and a minor part of C—S—H by means of IR and SEM microanalysis method.

摘要］ 针对隧道注浆工程用普通水泥水玻璃双液注浆材料存在凝胶时间不稳定、产物稳定性和抗地下水侵蚀性能差等主要问题，结合普通水泥水玻璃快速胶凝和碱激发硅铝质胶凝材料的特点，建立了高性能水玻璃悬浊型双液注浆材料的理想结构模型，并通过水泥复合偏高岭土水玻璃注浆材料的Na+固化性能和抗水溶蚀性能进行了试验验证，结合IR和SEM微观测试分析手段提出其组成结构应是以—Si—Al—H类沸石凝胶物质为主、C—S—H为辅的复合共存密实结构。

Through the trial regression to the ratio of unit injection well control area,unit well control area and injection-production well number ratio and shirr formula and unit injection well volume rate of change increasing with unit injection well control area decreasing,then Waterflooding reservoir macroscopica well spacing density formula c.

油藏工程理论及现场实践均表明，注水开发低渗油藏其注水方式和注采井数比对注水波及体积及水驱采收率有较大影响，通过对注水井水驱控制面积、单井控制面积与注采井数比进行了试探性回归分析，再结合谢尔卡乔夫公式，推导出了水驱采收率、驱油效率、井网指数、注采井数比与井网密度的关系式，从而建立了水驱油藏宏观井网密度公式。

It is embodied concretely:(1) With the adoption of grouting bolts, the cranny in wall rocks can be blocked up, the air can be isolated, the wall rocks can be prevented to be weatherized and make water, the strength of wall rocks can also be avoided to be lowered;(2) The lax broken wall rocks are commentated to a whole by liquid after they were grouted and the rock"s strength is increased, so the wall rocks become a part of the support structure by using itself and become a whole with the original rock, and the roadway is made to keep stable but not easy to be broken;(3) The spray layer wall are filled with liquid after grouting, the stress is avoided to be concentrated because the load could be evenly acted on the spray layer and the support;(4) The pressure acted on the plank can be delivered to the two sidepieces and then to the bottom by reinforcing the sidepiece; At the same time, the concentration degree of loads acted on the motherboard can be weaken because of the enlargement of the combination arch"s thickness, as result, the rock"s stress is lowered and the heaving is alleviated;(5) The common bolt is made to be fixed the whole length after grouting, the layers are connected to a integral whole and bear the weight of loads, so the support structure"s unity is increased.

具体体现在：(1)采用注浆锚杆注浆，可以利用浆液封堵围岩裂隙，隔绝空气，防止围岩风化，且能防止淋水和渗水，避免围岩被水浸湿而降低围岩的本身强度及造成的巷道变形。(2)注浆后浆液将松散破碎的围岩胶结成整体，提高了岩体强度，实现利用围岩本身作为支护结构的一部分，且与原岩形成一个整体，使巷道保持稳定而不易产生破坏；(3)注浆后使得喷层壁后充填密实，保证荷载能均匀地作用在喷层和支护上，避免出现应力集中点而首先破坏；(4)注浆后使作用在顶板上的压力能有效地传递到两帮，通过对帮的加固，又能把荷载传递到底板；同时由于组合拱厚度的加大，这样又能减小作用在底板上的荷载集中度，从而减小底板岩石中的应力，减轻底臌；(5)注浆加固后能使普通端锚锚杆实现全长锚固，它们共同将多层组合拱连成一体，共同承载，提高了支护结构的整体性。

Grouting in the around of infalling boundary and informing wall to prevent water based on clear knowning the condition of geology and hydrology. This method not only assure the safety of production but also protect the water resources around the colliery.

注浆封堵技术是在查清矿井水文地质条件的基础上，通过对进水区边界实施注浆工程，形成人为的挡水墙，从而阻断底板水的涌入，既解放了受水威胁的煤层又保证了矿井的安全生产，同时也保护了矿井周围水资源。

But note monlchamus, we should first of all, clearly a few details: if I'm using the print head integralization cartridge, note white without note, waydifferent spent cartridge, and throw away, it would be better then reuse, even when printed, generally does not have any prejudice to the printer; if the print head and the wall split-printer ink cartridges, ink in the note, we'd better choose the original manufacturer's selection of ink, because, the printer manufacturers compatible ink normally eligible for canceling the user's warranty, if inadvertently broke the print head and is concentrating.

但在注不朱后，我们答首不后澄辉几个梗概：假如我用的是打印脚一体化不朱盒，那么不注白不注，横竖不朱盒也不有什么用了，与其扔失，不立不如再宝贝诳骗，不离算打印不败果不抱负，凡是也不会差打印机有什么保护；假如用的是打印脚与不朱盒分体的打印机，那么在轻注不朱水时，我们最坏拔取原厂的不朱水，因为采取兼容不朱水，打印机厂家凡是城市裁撤用户的保修资格，给是失慎不弄好了打印脚，不离真是因小失不小了。

By calculation of water flow into tunnel and theoretical analysis for effect of blocking grouting circle combined with engineering analogy,the design principle and project of waterproofing and drainage system for Xiamen Subsea Tunnel were performed.

通过对隧道涌水量进行计算，对堵水注浆圈作用进行分析并结合工程类比后，分析确定了厦门海底隧道的防排水设计原则及方案，即在主隧道不良地质地段和整个服务隧道采用全封堵方案，水压按全水头计算；在主隧道完整围岩地段采用限量排放方案，水压可进行一定折减。

要解决这一问题、彰显穴灌坐水播种的优势就必须正确认识灌溉冲击水柱在沟内的水力特性，特别是灌溉水注对种沟沟底的冲击压力特性。

It emerged from the sea dripping a trail of green, glistening seaweed; spouts of water gushed in fountains from fields that lent it the sheen of an emerald.
