Then the pile-soil stress characteristics and stabilizing mechanism of the composite foundation are fully discussed. Based on the close analysis of the influence factors of the vertical bearing capacity, circular aperture extension theory is employed to establish the computing formulas for the pile vertical stress and the foundation vertical bearing capacity, respectively. Moreover, with analyzing the features of the calculation parameters such as materials of gunite mortar, jet pressure, diameter of the jet pipe, pile length, pile layout, a design theory for chemical churning pile composite foundation is proposed.

And methods to decide pile-soil stress ratio and the compressive modulus are developed. Meanwhile, the corresponding design method and the design parameters are proposed. In addition, studies for construction technique and quality detection of the chemical churning pile composite foundation are presented.

But after innumerable fluttering thoughts, like a man perfectly confused and out of myself, I came home to my fortification, not feeling, as we say, the ground I went on but terrify'd to the last degree, looking behind me at every two or three steps, mistaking every bush and tree, and fancying every stump at a distance to be a man; nor is it possible to describe how many various shapes affrighted imagination represented things to me in, how many wild ideas were found every moment in my fancy, and what strange unaccountable whimsies came into my thoughts by the way.

但是，这里没有想象的余地，有的只是那个脚印，那不是想象中的。可是浮想联翩之后，我仍然困惑不解，且六神无主了。因为心里感觉不舒服，我就回家加固房子，做好防御准备。通常我们说，走路时心惊胆战，便会两三步一回头。就这样我把那些树丛都误以为是人了，踏着每一步都在想象远处有一个人。这种经历是难以描述的，我的脑海中呈现出各种想象的可怕的影子，我的幻想中时时刻刻都有很多不可思议的想法，一路上我产生了很多莫名其妙的怪念头。
