The following results are got:(1) the analytical equation between the overburden pressure, the pore fluid pressure and the matrix stress is established;(2) the nonlinear relation between the porosity of saturated soils and the pore fluid pressure are obtained, which relates to the initial state and the initial pore pressure of saturated soils;(3) Based on the new principle, the rock shear strength theory and hydraulic fracturing pressure formulation are reacquired, which are much more reasonable than the traditional ones.

第二章讲述的是该有效应力原理的一些工程应用研究，通过该研究，我们取得如下成果：（1）建立了上覆岩层压力、孔隙流体压力、基岩应力之间的解析关系式；（2）推导出了饱和土体孔隙度与孔隙水压之间的非线性关系式，该关系式与多孔介质的初始状态及初始孔隙水压有关；（3）建立了基于多孔介质的岩石剪切强度理论和岩石破裂压力计算公式。

The study on petrology, geochemistry and isotope geology indicates that there are the common resource and tectonic setting for the Kangbutiebao formation with metamorphic volcanic rocks and the granite plutons related to the main iron deposits.They are different facies from magma evolvement in late Silurian-early Devonian.

岩石学、岩石地球化学及同位素研究表明，康布铁堡组变质火山岩、与主要铁矿床有关的花岗岩具有同源、同构造环境特征，是晚志留世-早泥盆世岩浆演化的不同相。

A preliminary study shows that the Honggong pluton, formally considered as typical I-type granite rock, is proved to be of aluminous A-type.

初步研究表明，以往被认为是典型的I型花岗岩质岩石的浙江洪公岩体应为铝质A型花岗岩质岩石。

Rock, usually limestone, composed of oolites.

岩石岩石，通常指石灰岩，由鲕粒岩组成

Pilot core processing devices designed and role is removed from the core for rock mechanics studies, and thus a more perfect, rational and broken rock mechanics research studies and three roller bits work for the design and improvement of the provision of the necessary bits of information.

试验岩芯加工装置的设计目的和作用是从岩石中取出岩芯以供力学研究，从而建立更加完美的，合理的岩石破碎学研究和牙轮的工作力学研究，为钻头的设计和改进提供必要的信息。

Up in the mountains are clear lakes, quick-moving small rivers, and huge formations of rock. One huge rock is called Half Dome. It rises more than two thousand seven hundred meters into the air.

在山中，有清蓝的湖泊、有快速流动的小河流，还有巨大的岩石群，其中一个最大的岩石叫半圆丘，它高达2700米，直插云宵。

Based on the selection of similar structure, a method for predicting the rock drillability of wildcat well is proposed.

该方法首先应用已钻相似构造井的地震资料、测井资料以及岩心测试资料，建立岩石可钻性钻前预测遗传神经网络模型，然后将神经网络与遗传算法有机结合起来，以神经网络理论为基础，利用遗传算法优化隐含层神经元个数和网络连接权值，最后利用野猫井的地震资料进行岩石可钻性钻前预测。

This rock formation is made of white-gray quartzite, a kind of sandstone. It is about three hundred meters above the river that flows below. When the sun shines on the almost straight-sided rocks, they look like bright shining wings rising out of a mountain of green trees.

这种岩层是由灰白的石英岩形成的，这是一种沙岩，它位于河流上方的大约三百米处，当太阳光垂直照射在这些岩石上时，这些岩石看起来就像是鲜艳明亮的翅膀从绿树环抱的大山中冉冉升起。
